Abstract :
Donor-acceptor crystalline hybrid materials are a new type of photoactive hybrid complex composed of two semiconductor components at the molecular level. Naphthalenediimide (NDI) and perylenediimide (PDI) based donor-acceptor crystalline hybrid materials have garnered significant interest in recent years owing to the structural diversity of the inorganic semiconductors and excellent redox activity in the NDI/PDI, which can effectively achieve long-lived charge separation and transfer under irradiation. In this review, we summarize recent research progress in the construction of NDI/PDI-based crystalline hybrid materials using POMs, metal halides, and transition-metal ions, and their applications in photochromism, photo-controllable fluorescence/ phosphorescence, photocatalytic organic transformations, and photothermal conversion, and as antibacterials, to provide useful guidance for the design, preparation and application of these materials in the future.

Abstract :
Photochromic materials and room-temperature phosphorescence (RTP) are essential for applications in optoelectronics and bioimaging. Organic-inorganic hybrid materials, particularly those exhibiting donor-acceptor (D-A) characteristics through supramolecular interactions, have shown significant potential to integrate both photochromic and RTP properties. Among them, the anion-pi and pi-pi interactions have been extensively studied; however, the role of anion-pi-pi interactions in hybrid materials remains largely unexplored. This study investigated three naphthalenediimide-polyoxometalate (NDI-POM) hybrids: (H2DMAP-NDI)(HPW12O40)(NMP)2 (1), (HDMAP-NDI)2(HPW12O40)(NMP)2 (2), and (HDMAP-NDI)2(HPW12O40)(NMP)7 (3), focusing on the impact of anion-pi-pi interactions on their photochromic and RTP properties. The results indicate that hybrid 1 exhibits the fastest photoresponse and highest RTP quantum yield, primarily driven by anion-pi interactions. Hybrid 2, which involves anion-pi-pi interactions, shows slower photochromism and lower RTP yield due to exciton localization and nonradiative decay paths resulting from pi-pi stacking. Hybrid 3, characterized by excessively strong interactions, is unstable and nonemissive. This study provides valuable insights into the role of anion-pi-pi interactions in hybrid materials and offers a framework for designing advanced photoresponsive materials with tunable properties for diverse applications.

Abstract :
Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) is a widely used anode interlayer (AIL) in organic solar cells (OSCs). However, the intrinsic acidity and hygroscopic nature of PSS ions in PEDOT:PSS have been proven to cause electrode corrosion and deteriorate device performance. Herein, a straightforward method is reported to enhance the water resistance of PEDOT:PSS by incorporating tris[bis(methoxymethyl)amino]-1,3,5-triazine (HM) as a cross-linker. The cross-linking reaction between PSS and HM neutralizes the acidity of PEDOT:PSS and forms a stable, hydrophobic network. Additionally, the aggregation morphology of PEDOT:PSS was regulated by HM, improving the conductivity and work function, thereby resulting in enhanced hole extraction and transport ability. Devices incorporating PEDOT:PSS-HM demonstrated improved power conversion efficiency (PCE) of 19.03% compared to 17.88% for those using standard PEDOT:PSS. The neutral pH and water-resistant nature of PEDOT:PSS-HM effectively improved the long-term stability of OSCs with a T80 of over 400 h under continuous illumination. Moreover, after aging the PEDOT: PSS-HM film for 216 h at 80% relative humidity and 40 degrees C, it can be still used as AIL to fabricate efficient OSC devices. This work presents a simple and effective approach to preparing a non-corrosive and stable PEDOT derivative, offering valuable insights for the development of high-performance AIL materials.

Abstract :
Harnessing supramolecular interactions to regulate the structure and performance of functional materials is a key challenge in materials chemistry. Herein, the study utilizes 18-crown-6 (18C6) ether-assisted alkali-metal (Na, K, Cs) copper(I) iodide supramolecular assemblies to precisely regulate the material structures. This approach facilitated the transition from 1D mono-royal crown coordination (18C6@KCuI2, CKCI) to 0D di-royal crown ((18C6)(2)@Na-2(H2O)(3)Cu4I6, CNCI) and tri-royal crown ((18C6)(3)@Cs2Cu2I4, CCCI) structures. Interestingly, the CCCI single-crystal exhibits outstanding scintillation properties, with a high relative light yield of 71 000 photons MeV-1 and an ultralow detection limit of 39.3 nGy s(-1), which can be attributed to the synergistic effects of 18C6 and copper-iodide clusters. It stabilizes the self-trapped exciton state, enhances exciton localization, and reduces non-radiative losses, thus resulting in a large Stokes shift of 193 nm and near-unity photoluminescence quantum yield of 99.4%. Additionally, 18C6 can promote crystal nucleation and growth, making it easy to prepare centimeter-scale transparent single crystals with >80% transmittance, such as CCCI single crystal can achieve an ultrahigh-resolution X-ray imaging of 26.3 lp mm(-1). It demonstrates that the structure and performance of halide scintillators can be regulated through supramolecular interactions, which provides a new approach for developing high-performance scintillator materials.

Abstract :
Rylene diimides are an attractive class of organic dyes owing to their exceptional optical properties and optoelectronic applications. Herein, we extend their applications to the realm of X-ray imaging. The emissive 1,1′-bi(2-naphthol-4,5-dicarboximide) (BiND-OH) and its phenyl/methyl derivatives, BiND-OPh and BiND-OMe, have been selected to investigate the structure-activity relationships between their crystal packing and X-ray scintillation properties. Single crystal X-ray diffraction results indicate that BiND-OH forms a tightly structured conformation with two interlocks by hydrogen bonding, leading to a charge transfer state and resulting in nearly non-scintillation. In contrast, the radioluminescence intensities of BiND-OPh and BiND-OMe have increased by about 73 and 537 times, respectively, owing to the disruption of hydrogen bonding control and the formation of a J-aggregation fraction dominated by π-π interactions. Remarkably, BiND-OMe displays superior scintillation properties, marked by reduced non-radiative transitions, attributed to greater π-π plane distances, extended slip distances, and diminished π-plane overlap areas. It demonstrates a low detection limit of 70.68 nGy s−1 and a short decay time of 4.37 ns. When applied to X-ray imaging, it produces a high spatial resolution of 11.0 lp mm−1. This finding provides valuable insights into the profound impact of molecular structure and aggregation state on the organic scintillation properties. (Figure presented.) © Science China Press 2024.

Abstract :
Chiral self-discrimination plays a critical role in supramolecular chemistry and materials science. However, an ideal strategy for achieving chiral self-discrimination remains elusive due to the inevitable nonspecific binding of incorrect enantiomers, and insufficient intrinsic optical activity of chiral molecules. Herein, a novel 1,1′-binaphthol (BINOL) derivative with an imide group fused at the peri-position of one naphthol scaffold is developed, which combines the dual functionalities of aggregation-induced emission characteristic of BINOLs, and high emission of 1,8-naphthalimides. The multiple molecular recognition between two hydroxyl groups in BINOL units and two carbonyl groups in 1,8-naphthalimide moieties endows the precise chiral self-discrimination behaviors. As expected, the homochiral aggregates exhibit reversible phase transitions, switching from non-emission to bright green emission upon absorption and desorption of methanol vapor. In contrast, the heterochiral conglomerates exhibit irreversible yellow emission changes due to the impact of chiral self-discrimination. Such chiral self-discrimination-induced luminescence vapochromism can be further applied to high-level anti-counterfeiting and data encryption. This work provides a new perspective on smart chiral organic materials based on chiral self-discrimination. © 2024 Wiley-VCH GmbH.

Abstract :
Semiconductive metal-organic frameworks (MOFs) with donor-acceptor (D-A) characteristics have garnered attractive attention due to their capacity for separating and transferring photogenerated charges, making them promising candidates for high-performance X-ray detectors. However, the low charge transfer efficiency between the metal nodes and organic ligands limits the X-ray-to-electricity conversion efficiency of these materials. Herein, an additional photoactive donor (D') is introduced by incorporating a heavy atom-containing polyoxometalate (POM) [alpha-SiW12O40](4-) into a binary {[Ni center dot bcbp center dot(H2O)(2)] center dot(H2O)(4) center dot Cl}(n) (Ni-bcbp, bcbp: H(2)bcbp center dot 2Cl = 1,1'-bis (4-carboxyphenyl)(4,4'-bipyridinium) dichloride) MOF, resulting in a semiconductive ternary D-D'-A framework {[Ni-2(bcbp)(2) center dot(H2O)(4) center dot(DMA)] center dot(SiW12O40)}(n) (SiW@Ni-bcbp, DMA: dimethylacetamide). The obtained material features an unprecedented porous 8-connected bcu-net structure that accommodates nanoscale [alpha-SiW12O40](4-) counterions, displaying uncommon optoelectronic responses. In contrast to binary Ni-bcbp, the SiW@Ni-bcbp framework exhibits distinctive photochromism and robust X-ray responsiveness, which can be attributed to the synergistic effects of the electron reservoir and multiple photoinduced electron transfer originating from the POMs. As a result, the X-ray detector based on SiW@Ni-bcbp demonstrates a sensitivity of 5741.6 mu C Gy(air)(-1) cm(-2) with a low detection limit of 0.49 mu Gy(air) s(-1). Moreover, the devices demonstrated the capability of producing clearness X-ray images, providing a feasible and stable solution for constructing high-performance direct X-ray detectors.

Abstract :
Mn-based metal halides scintillators with high photoluminescence quantum yield (PLQY) have recently emerged as promising large-size candidates for X-ray imaging but still remains as difficult challenge in stability and high processing temperatures. Here, three manganese halides are designed by introducing branched chains into organic cations and extending the carbon chains, namely (i-PrTPP)2MnBr4, (i-BuTPP)2MnBr4 and (i-AmTPP)2MnBr4, successfully lowered the melting point of manganese halides to 120.2 degrees C. Three materials show striking light yields of 59 000, 40 000, and 52 000 photons MeV-1, respectively. The lowest detection limits are 42.30, 50.92, and 45.71 nGy s-1, respectively. Meanwhile, compared to their counterparts with linear carbon chains, the introduction of branched chains has significantly enhanced the stability of the scintillators in the glass state. A transparent glass has been prepared using a melt-quenching method, which exhibited 80% transmittance at 400-700 nm. The glass is utilized for X-ray imaging, achieving a high spatial resolution up to 46.6 lp mm-1. This result provides a new approach to enhancing the performance of such scintillator materials.

Abstract :
X-ray imaging utilizing organic-inorganic hybrid metal halide (OIHMH) glassy scintillators has garnered significant attention. But their inferior radioluminescence makes achieving rapid image acquisition difficult, posing a persistent challenge for dynamic imaging. Herein, organic phosphonium halide side-chain engineering is proposed, introducing bulky aromatic rings at the alkyl chain ends, to improve the radioluminescence of OIHMHs. For Mn(II)-based OIHMHs, the (BUP)2MnCl4 (BUP = butyltriphenylphosphonium) powder has a low relative light yield (5400 photons MeV-1). After introducing a benzyl group, this value of (BnO-MTP)2MnCl4 (BnO-MTP = (benzyloxy)methyl) triphenylphonium) powder boosts to 60 000 photons MeV-1. The introduction of benzyl group can restrict molecular non-radiative vibrations, increase exciton binding energy, enhance electron-phonon coupling, and reduce self-absorption, thus significantly improving exciton utilization and scintillation performance of (BnO-MTP)2MnCl4. Besides, the transparent (BnO-MTP)2MnCl4 glass has a low melting point (167 degrees C) and high relative light yield (26 000 photons MeV-1). When applied to X-ray imaging, it can achieve static imaging with a spatial-resolution of up to 24.6 lp mm-1 and clear dynamic imaging under X-ray irradiation. Furthermore, this strategy also applies to Sb(III)-based OIHMHs with self-trapped exciton emissions, where (BnO-MTP)2SbCl5 exhibits superior scintillation performance compared to (BUP)2SbCl5, demonstrating its broad applicability in constructing high-performance OIHMH glassy scintillators.
