Abstract ：
Solar-driven photothermal chemical transformations are regarded as green processes to reduce energy consumption and are expected to utilize unique light-induced activation mechanisms to improve reaction kinetics. Halide perovskites and their derivatives, due to unique optoelectronic properties and compositional flexibility, are allowed for the precise regulation of energy band structures and surface electronic states, showing potentials as photoactivated catalysts with photo-thermal synergistic effects. However, the photothermal catalytic performance of halide perovskites is still unsatisfied with low conversion (<0.2%). Herein, Cs3BixSb2-xBr9 is designed as a novel and effective photothermal catalyst for light-driven degradation of ester under room temperature, achieving a near-unity conversion of approximate to 99% without external heating. Photothermal catalytic process shows the remarkable enhancementup to 796% and 200% compared with that in the single thermocatalysis or photocatalysis. The stable catalyst shows superior light-driven cyclic performance, as well. Mechanistic studies combined with in situ characterizations and theoretical calculations show that photon-bismuth hotspot with the synergy of photoinduced charge transfer process (photochemistry) significantly reduce the activation energy, light-to-heat effects (thermochemistry) elevate the local temperature, and bismuth active site promotes the C & horbar;O bond activation (surface adsorption), which together contribute to excellent solar-driven conversion efficiency on the perovskite derivative.

Abstract ：
C(sp3)-H activation of alcohols enables creating new C & horbar;C bond while keeping hydroxyl group in a step and atom economic manner. Here, we disclose a protocol of coupling alcohols with alkenes for C(sp3)-C(sp3) bond formation via heterogeneous photocatalysis in flow. This protocol functions well with a broad scope of alcohols (primary and secondary alcohols) and alkenes with moderate to good yields. The heterogeneous photocatalysis in flow enables current methodology to be conducted even on gram scale, exhibiting great potential for industrial applications. Cleavage of alpha-C(sp3)-H of alcohol is induced by S center dot species on the surface of ZnIn2S4 via hydrogen atom transfer (HAT), and this step was found to be involved in the rate-determining step.

Abstract ：
Hydrogels have received great attention due to their molecular designability and wide application range. However, they are prone to freeze at low temperatures due to the existence of mass water molecules, which can damage their flexibility and transparency, greatly limiting their use in cold environments. Although adding cryoprotectants can reduce the freezing point of hydrogels, it may also deteriorate the mechanical properties and face the risk of cryoprotectant leakage. Herein, the microphase-separated structures of hydrogels are regulated to confine water molecules in sub-6 nm nanochannels and increase the proportion of bound water, endowing the hydrogels with intrinsic anti-freezing properties, high mechanical strength, good stretchability, remarkable fracture energy, and puncture resistance. Even after being kept in liquid nitrogen for 1000 h, the hydrogel still maintains good transparency. The hydrogel can exhibit excellent low-temperature shape memory and intelligent optical waveguide properties. Additionally, the hydrogel can be assembled into strain and pressure sensors for flexible sensing at both room and low temperatures. The intrinsically anti-freezing microphase-separated hydrogel offers broad prospects in low-temperature electronic and optical applications.

Abstract ：
Clinical treatment of open wounds is challenging due to bacterial infection and biofilm protection. Antibiotics are commonly utilized as antibacterials; however, multidrug resistance (MDR) severely affects the therapeutic effect. Therefore, developing a non-antibiotic strategy for treating infections and accelerating wound healing is highly required. Herein, for the first time, an electronically inverted antiperovskite, InNNi3, has been demonstrated as a novel photothermal material with efficient and broad-spectrum anti-bacterial activity. Due to the quasi-continuous energy levels and inverse coordination with cations/anions exchanged in crystal sites, InNNi3 possesses a near-unity photothermal conversion efficiency (96.9%) and a positively charged surface, which together contribute to the high antimicrobial activity (99.9%) via photothermal activation and electrostatic interaction with pathogens, including methicillin-resistant Staphylococcus aureus (MRSA), Escherichia coli (E. coli) and Candida albicans (C. albicans) within several minutes. Moreover, as an effective antibiofilm agent, InNNi3 exhibits over 99% scavenging effect on biofilms. An accelerated healing rate for infected wounds has also been achieved using an InNNi3-treatment strategy under NIR irradiation by reducing inflammation, promoting collagen deposition, boosting early expression of CD31 and facilitating the regeneration of dermis and skin appendages. The excellent biocompatibility of InNNi3 further demonstrates its great potential for clinical applications in future.

Abstract ：
Broadband emissive perovskites are next-generation materials for solid-state lighting and radiative detection. However, white-emitting perovskites are generally synthesized by regulating B/X sites, while not enough attention is paid to the A-site, which is thought to hardly affect the band-edge structures and optoelectronic properties. Here, a series of Sb3+-doped In-based 0D halide perovskite derivatives are described with various organoammonium cations in A-sites. Warm-white light emitting across the visible spectrum (450-850 nm), large Stokes shifts, and high photoluminescence quantum yields are easily tunable by molecularly tailoring A-site cations. These features enable a light yield up to 60976 Photons/MeV as X-ray scintillator, and a detection limit of 90 nGyair/s that is approximate to 60 times lower than the medical requirement. It is proved that A-site plays a critical role in determining the degree of distortion of polyhedra, which influences the broadband photoluminescence and self-trapped exciton (STE) dominates the emission process. Moreover, for the first time, via the incorporation of 2,6-dimethylpiperazine, a mixed A-site regulating strategy produces a standard white-light emission, which originates from the blue-light and yellow-light related to various STE emission centers. It is foreseen that this strategy highlights the expanded role of A-site and the importance of rethinking A-sites in perovskites. Efficient and tunable broadband warm-white emission is achieved by engineering the A-site organoammonium cations in Sb-doped In-based 0D perovskite derivatives, with visible light emitting, large Stokes shift, high photoluminescence yield, and X-ray scintillation. For the first time, a standard white-light emission is realized by a mixed A-site regulation strategy by the incorporation of another functional organic amine cation.image

Abstract ：
Light-to-heat conversion represents one of the most promising pathways to utilize full-spectrum solar energy. The key for boosting the photothermal conversion in semiconductor-based light absorbers relies on narrowing the bandgap for harvesting wide-range sunlight and localizing thermal energy via decreasing heat loss. Here, we demonstrate the first example of using a halide perovskite, Cs4CuSb2Cl12, as the photothermal material for efficient solar-to-heat conversion, with an intrinsic narrow bandgap and ultralow thermal conductivity. Full-spectrum (200-2500 nm) absorption and solar-thermal conversion efficiency up to 93.4% are achieved. The photothermal property enables a low-temperature and rapid hydrogen production from ammonia borane, with 2.0 equiv of hydrogen released, and a photothermal activation efficiency of 12.2% is realized, without any extra energy input. This high photothermal performance not only provides a potential for an energy-efficient on-board hydrogen supply for fuel cells but also opens up a new field for halide perovskites utilized as photothermal convertors.

Abstract ：
Co-catalysts are commonly employed as catalytic centers to activate reactants and intermediates for driving redox reactions with photogenerated carriers during photocatalysis. Herein, a group of electronically inverted perovskite-type nitrides CuxIn1-xNNi3 (0 <= x <= 1) are reported as novel and versatile co-catalysts for the significantly enhanced photocatalytic hydrogen production performance on various photocatalysts, such as metal sulfides (CdS, ZnIn2S4), carbon nitride (g-C3N4), and metal oxide (TiO2), respectively. The hybrid photocatalyst Cu0.5In0.5NNi3/CdS exhibits an optimal activity up to 6945 mu mol g-1 h-1 and a remarkable enhancement factor of 6146% compared with that of pristine CdS. Besides, a high reaction stability with repetitive photocatalytic cycles is achieved. The obvious improvement of activity can be ascribed to the promoted charge separation of energetic carriers due to the metallic properties of CuxIn1-xNNi3 and abundant Ni active sites. A near-zero Gibbs free energy of adsorbed atomic hydrogen on the Ni-site is thermodynamically favorable for hydrogen evolution, which can be regulated by electronic states of A-sites (Cu/In). This work not only demonstrates the great potential of perovskite-structured nitrides as a universal platform for enhanced photocatalysis but also addresses the importance of exploring new catalytic applications for unique perovskite-derivatives with cations/anions exchanged in coordinated sites of polyhedral. For the first time, an electronically inverted perovskite CuxIn1-xNNi3 (0 <= x <= 1) nitride is demonstrated as a novel, efficient, robust, and universal co-catalyst for significantly enhanced photocatalytic hydrogen production on various widely used photocatalysts (CdS, ZnIn2S4, TiO2, and g-C3N4), with enhancement factors of activity as 6146%, 327%, 1889% and 450%, respectively. image

Abstract ：
Halide perovskites and derivatives have been used as emerging photocatalysts due to their unique optoelectronic and structural diversity. However, compared with the well-explored photophysical processes for light-driven more energetic carriers to trigger redox reactions, catalytic effects on the surface of halide perovskite or their derivatives for chemical transformations between reactive species are seldom addressed, which is equally important for improving the efficiency for halide perovskite-based photocatalysts. Here, we demonstrate that Cs3Bi2Br9 sites in the Cs3Bi2Br9/CdS heterojunction, not only participate in light-driven processes, but also play a vital role for the activation and conversion of key intermediates during C(sp3)-H bond transformation, via a more thermodynamically and kinetically favorable surface reaction pathway. Besides, various aromatic hydrocarbons can be effectively photocatalytic converted to corresponding aldehydes/ketones as major products. This work highlights the importance of surface catalysis mechanism in photocatalysis not only for halide perovskites but also for other semiconductors.

Abstract ：
The preparation of 3D functional isolated mesoscopic assemblies remains a challenge in the self-assembly of polymers. Here, well-defined 3D hexagonal and hexagram prisms with uniform dimensions are acquired by the crystallization of the inclusion complex composed of a crystalline molecule tris-o-phenylenedioxycyclotriphosphazene (TPP) and a block copolymer. The crystalline TPP plays an important role in the self-assembling process. The faceted morphologies of the hexagonal and hexagram prisms are infrequent in the self-assembly field of soft materials. The formation of the prisms experiences a 3D growth mechanism. The epitaxial growth, accompanied by the heterogeneous nucleation in the edges, yields the growth of inclusion crystals. This study provides a path to construct well-defined polymeric soft materials with broad utility based on numerous supramolecular complexes.
