Abstract :
Tumor-selective near infrared-induced photothermal therapy is a successful approach for ablation of malignant and cancerous cells. In the NIR region, tissue penetration depth in the near-infrared second region (NIR-II, 1000-1700 nm) is deeper than that of the traditional near-infrared first region (NIR-I, 700-900 nm) for the lower scattering and absorption. However, there are few photothermal conversion agents (PCAs) in the NIR-II. And these PCAs are quickly identified by the immune system and rapidly cleared by the reticuloendothelial system (RES), leading to low accumulation in tumor, which prevents further advanced clinical practice. In this work, the conjugated polymer, PBTPBFTDPP, is prepared and assembled into nanoparticles (SPN). Then, the genetically engineered cell membranes are coated on the surface of SPN to obtain the positive targeting ability (SPN-TF). The obtained SPN-TF nanoparticles exhibit an excellent photothermal conversion ability, predominant targeting efficiency, and superb photothermal therapy for anticancer both in vitro and in vivo. These works will inspire more translational work on SPN for future clinical applications.

Abstract :
Photothermal therapy (PTT), a powerful tool for non-invasive cancer treatment, has been recognized as an alternative strategy for cancer therapy in the clinic, and it is promoted by optical absorbing agents (photothermal agents) that can intensively convert near-infrared (NIR) light into thermal energy for cancer ablation. Conjugated polymer nanoparticles (CPNs) have recently attracted extensive attention owing to their excellent photothermal properties. However, the absorption of typical CPNs is mostly located in the traditional near-infrared region (NIR-I, 700-900 nm), which suffers from low tissue penetration, so the penetration depth is still limited and severely restricts their further applications. Compared with the NIR-I light, the second near-infrared window light (NIR-II, 1000-1700 nm) could efficiently enhance the tissue penetration depth, however, CPNs which absorb NIR-II region light are still especially limited and need further exploration. Here, a thieno-isoindigo derivative-based Donor-Acceptor (D-A) polymer (BTPBFDTS), which exhibited excellent absorption characteristics from the NIR-I to NIR-II window, was prepared. After formation of nanoparticles and surface functionalization, the prepared nanoparticles (NPs(BTPBFDTS)@HA NPs) exhibited obvious targeting ability, high photothermal conversion efficiency and photoacoustic imaging effects under 1064 nm irradiation. Bothin vitroandin vivostudies demonstrate that our obtained NPs(BTPBFDTS)@HA nanoparticles possess excellent PTT efficacy including extremely high cancer cell killing ability and admirable tumor elimination efficiency. Hence, this work developed a promising photothermal conversion agent based on CPNs for cancer ablation.

Abstract :
Four novel compounds (1-4) were synthesized using 2-phenyl-4H-1-benzopyran-4-one (flavone) moiety as an acceptor and phenoxazine, phenothiazine, 9,9-dimethyl-9,10-dihydroacridine, diphenylamine as donors. Their photophysical properties were studied with spectroscopic and theoretical methods. The results show that 1 and 2 exhibit good aggregation-induced emission (AIE) properties in tetrahydrofuran (THF)/water mixtures, whose maximum photoluminescence (PL) intensities are 156- and 187-fold higher than those in pure THF solutions, and can reach 256- and 506-fold higher than those in the mixtures at water fractions of 50%, respectively. 3 displays similar PL property except for obvious emission in pure THF solution. However, PL intensity of 4 decreases with an increase in water fraction, and then is enhanced with further increase in water fraction. Moreover, 4 shows high quantum yields both in toluene solution (0.61) and in solid state (0.83). It exhibits a positive sol-vatochromism. In addition, 2 possesses mechanofluorochromic transition from sky blue to yellow after grinding. It can also be applied in live-cell imaging.

Abstract :
To develop high performance anion exchange membranes (AEMs), a novel bisphenol monomer bearing eight benzylmethyl groups at the outer edge of the molecule was synthesized, which after condensation polymerization with various amounts of 4,4'-dihydroxydiphenylsulfone and 4,4'-difluorobenzophenone yielded novel poly(arylene ether)s with densely located benzylmethyl groups. These benzylmethyl groups were then converted to quaternary ammonium groups by radical-initiated bromination and quatemization in tandem, leading to the emergence of densely quaternized poly(arylene ether sulfone)s (QA-PAEs) with controlled ion exchange capacities (IECs) ranging from 1.61 to 2.32 mmol g(-1). Both small-angle X-ray scattering (SAXS) and transmission electron microscopy (TEM) studies revealed distinct phase separation in the QA-PAEs. The QA-PAE-40 with an IEC of 2.32 mmol g(-1) exhibited a Br- conductivity of 9.2 mS cm(-1) and a SO42- conductivity of 14.0 mS cm(-1) at room temperature, much higher than those of a control membrane with a similar IEC but without obvious phase separation. Therefore, phase separation of AEMs was validated to be advantageous for the efficient conducting of anions. The experimental results also showed that the QA-PAEs were promising AEM materials, especially for non-alkaline applications.

Abstract :
Four compounds (TM-1 similar to 4) based on N-(4-trifluoromethylphenyl)phenothiazine-S,S-dioxide and N-[3,5-bis(trifluoromethyl)phenyl]phenothiazine-S,S-dioxide are synthesized by Buchwald-Hartwig cross coupling reaction. The effect of different substituents in acceptors on the electronic, photophysical and electrochemical properties are studied by UVVis, fluorescence spectroscopy, cyclic voltammetry curves and theoretical calculations. The energy gaps (Delta E-ST) between singlet excited states (S1) and triplet excited states (T-1) of these compounds decrease by addition of one para-substituted -CF3 or two meta-substituted -CF3 on N-phenyl in order to enhance the electron-withdrawing capability of the acceptors. Small Delta E-ST of these compounds range from 0.09 eV to 0.18 eV. TM-2 similar to 4 exhibit thermally activated delayed fluorescence (TADF) characteristics with short delayed fluorescence lifetimes (tau(d)) within 0.69-1.16 mu s. TM-3 emits blue light with an emission wavelength of 475 nm. (C) 2016 Elsevier Ltd. All rights reserved.

Abstract :
We report on the synthesis and characterization of a series of donor acceptor copolymers (PF1, PF2, PF3 or PF4) based on a dinaphtho-s-indacene (DNI) donor unit and four different acceptor units. The molecular weights of the copolymers were determined by using gel permeation chromatography, and their electrochemical properties were investigated by cyclic voltammetry. All four copolymers showed deeplying highest occupied molecular orbital energy levels. Inverted bulk heterojunction solar cells were fabricated by using the synthesized copolymers as the electron donor material and 6,6-phenyl-C71-butyric acid methyl ester (PC71BM) as the electron acceptor material. Inverted solar cells based on PF1:PC71BM (1:4, w/w) exhibited a power conversion efficiency (PCE) of 3.07%, a high open-circuit voltage (v(oc)) of 0.99 V, a short-circuit current density U-sc) of 7.85 mA/cm(2), and a fill factor of 39.5% under the AM1.5G illumination. With the same fabrication method, the inverted devices based on PF2, PF3 and PF4 showed PCEs of 2.62, 1.18 and 1.32%, and 1/0, values of 0.97, 0.91 and 0.80 V, respectively. (C) 2014 Elsevier Ltd.

Abstract :
A novel route is introduced to synthesize hierarchical polyaniline-grafted reduced graphene oxide (rGO) hybrid materials by polyaniline nanorods covalently bonded on the surface of rGO. Aminophenyl groups were initially grafted on rGO via diazonium treatment. Then the PANI nanorods were aligned vertically on rGO to construct a three-dimensional (3D) structure. The 3D structure could shorten the electronic transmission path and form abundant space for electrolyte ions. The hybrid materials fabricated as supercapacitor electrodes exhibited a maximal specific capacitance of 1045.51 F g(-1), and the energy density (E) could achieve an upper value of 8.3 Wh kg(-1) at the current density of 0.2 A g(-1) simultaneously. Such highly stable three-dimensional structural materials are very promising for the next generation of high-performance electrochemical supercapacitors.
