Linked-Acceptor Type Conjugated Polymer for High Performance Organic Photovoltaics with an Open-Circuit Voltage Exceeding 1 V
Xia, Benzheng; Lu, Kun; Zhao, Yifan; Zhang, Jianqi; Yuan, Liu; Zhu, Lingyun; Yi, Yuanping; Wei, Zhixiang
A linked-acceptor type conjugated polymer is designed and sythesized based on 4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzodithiophene (BDTT) and linked-thienopyrrole-4,6-dione (LTPD). This polymer uses alkyl-substituted thiophene as a bridge. The PBDTT-LTPD includes two TPD units in one repeating unit, which can enhance acceptor density in the polymer backbone and lower the…
Polymerization-induced self-assembly of liquid crystalline ABC triblock copolymers with long solvophilic chains
Huo, Meng; Wan, Zhengyi; Zeng, Min; Wei, Yen; Yuan, Jinying
Understanding the self-assembly of liquid crystalline (LC) block copolymers is challenging because of the complex influencing factors. In this article, we studied the influence of the solvophilic chain length on the self-assembly of the LC ABC triblock copolymer poly(N,N-dimethylaminoethyl methacrylate)-b-poly(benzyl methacrylate)-b-poly…
Study on phase transition behavior and lamellar orientation of uniaxially stretched poly(ʟ-lactide) / cellulose nanocrystal-graft-poly(d-lactide) blend
Nagarajan, Selvaraj; Hu, Jian; Wu, Hao; Duan, Yongxin; Zhang, Jianming
Towards the development of high-performance green composites, the surface functionalized cellulose nanocrystals (CNC) have been widely used as reinforcement along with biopolymer. In our previous work, it has been demonstrated that CNC grafted with PDLA (CNC-g-PDLA) could improve the crystal nucleation density and heat distraction ability of PLLA matrix via…
Effect of high molecular weight on pore formation and various properties of microporous membrane used for lithium-ion battery separator
Xu, Guan; Ding, Lei; Wu, Tong; Xiang, Ming; Yang, Feng
In this article, iPP cast films with high molecular weight in middle layer were prepared to investigate the effect of high molecular weight component on pore formation and mechanical strength. The results of DSC, SEM and 2D-XRD indicated that higher molecular weight and die draw ratio (DDR) would not alter…
Contribution to Accurate Spherical Gold Nanoparticle Size Determination by Single-Particle Inductively Coupled Mass Spectrometry: A Comparison with Small-Angle X-ray Scattering
Geertsen, Valérie; Barruet, Elodie; Gobeaux, Frédéric; Lacour, Jean-Luc; Taché, Olivier
Small-angle X-ray scattering spectroscopy (SAXS) is the method of choice for nanoparticle diameter and concentration determination. On the one hand, it is metrologically traceable for spherical nanoparticle mean diameter determination and does not require any sample preparation or calibration. On the other hand, single-particle inductively coupled mass spectrometry (SPICPMS) is…
Liquid Crystalline Nanoparticles as an Ophthalmic Delivery System for Tetrandrine: Development, Characterization, and In Vitro and In Vivo Evaluation
Liu, Rui; Wang, Shuangshuang; Fang, Shiming; Wang, Jialu; Chen, Jingjing; Huang, Xingguo; He, Xin; Liu, Changxiao
The purpose of this study was to develop novel liquid crystalline nanoparticles (LCNPs) that display improved pre-ocular residence time and ocular bioavailability and that can be used as an ophthalmic delivery system for tetrandrine (TET). The delivery system consisted of three primary components, including glyceryl monoolein, poloxamer 407, and water,…
Liquid Crystals of Self-Assembled DNA Bottlebrushes
Storm, Ingeborg M.; Kornreich, Micha; Hernandez-Garcia, Armando; Voets, Ilja K.; Beck, Roy; Cohen Stuart, Martien A.; Leermakers, Frans A. M.; de Vries, Renko
Early theories for bottlebrush polymers have suggested that the so-called main-chain stiffening effect caused by the presence of a dense corona of side chains along a central main chain should lead to an increased ratio of effective persistence length (lp,eff) over the effective thickness (Deff) and, hence, ultimately to lyotropic…
High efficiency non-fullerene organic solar cells without electron transporting layers enabled by Lewis base anion doping
Wang, Rong; Zhang, Dongyang; Xie, Shenkun; Wang, Jianqiu; Zheng, Zhong; Wei, Donghui; Sun, Xiaobo; Zhou, Huiqiong; Zhang, Yuan
Interfacial charge extraction and recombination play a critical role in photovoltaic characteristics of organic bulk heterojunction solar cells. Here we propose a methodology based on Lewis base n-doping with tetrabutylammonium acetate (TBAA) salts to boost charge extraction and resultant power conversion efficiencies (PCE) in OPVs with non-fullerene acceptors (NFA). Based…
Unexpected Synthesis of Segmented Poly(hydroxyurea–urethane)s from Dicyclic Carbonates and Diamines by Organocatalysis
Bossion, Amaury; Aguirresarobe, Roberto H.; Irusta, Lourdes; Taton, Daniel; Cramail, Henri; Grau, Etienne; Mecerreyes, David; Su, Cui; Liu, Guoming; Müller, Alejandro J.; Sardon, Haritz
A complete study of the effect of different organocatalysts on the step-growth polyaddition of a five-membered dicyclic carbonate, namely diglycerol dicarbonate, with a poly(ethylene glycol)-based diamine in bulk at 120 °C was first carried out. The reaction was found to be dramatically catalyst-dependent, higher rates being observed in the presence…
