A new donor–acceptor (D–A) conjugated copolymer based on benzo[1,2‐b:4,5‐b′]dithiophene (BDT) and thieno[3,4‐c]pyrrole‐4,6‐dione (TPD) was synthesized via a Stille cross‐coupling reaction. A highly conjugated thiophene‐based side group, tris(thienylenevinylene) (TTV), was incorporated into each BDT unit to generate the two‐dimensional D–A copolymer (PBDT‐TTV). An alkoxy‐substituted BDT‐based TPD copolymer
一种基于苯并[1,2- b:4,5- b ']二噻吩(BDT)和噻吩[3,4- c ]的新型供体-受体(DA)共轭共聚物通过Stille交叉偶联反应合成了]吡咯-4,6-二酮(TPD)。将高度共轭的基于噻吩的侧基三(噻吩乙烯撑)(TTV)结合到每个BDT单元中,以生成二维D–A共聚物(PBDT-TTV)。使用相同的聚合方法合成了烷氧基取代的BDT基TPD共聚物(PBDT-OR)进行比较。PBDT-TTV薄膜产生两个不同的吸收峰。较短的波长吸收(458 nm)归因于包含TTV组的BDT单元,而较长的波长带(567–616 nm)归因于BDT供体与TPD受体之间的分子内电荷转移。PBDT-OR和PBDT-TTV的最高占据分子轨道能级分别为-5.53和-5.61 eV。PBDT-TTV薄膜收获了覆盖300-700 nm范围的宽广的太阳光谱。与PBDT-OR薄膜的比较显示,PBDT-TTV薄膜中更

A series of symmetrical D-pi-A-pi-D molecules based on benzothiadiazole and oligo(thienylenevinylene)s were facilely developed. The investigation of their photophysical and electrochemical properties demonstrated that these compounds exhibited broad absorption covering the whole visible range with appropriate energy levels for light-harvesting donors.

Two fluorescentheteroditopic ligands (2a and 2b) for zincion were synthesized and studied. The efficiencies of two photophysical processes, intramolecular charge transfer (ICT) and photoinduced electron transfer (PET), determine the magnitudes of emission bathochromic shift and enhancement, respectively, when a heteroditopic ligand forms mono- or dizinc complexes. The electron-rich 2b is characterized
合成并研究了锌离子的两种荧光异双位配体(2a和2b)。当异双位配体形成单或二锌复合体。富电子2b的特点是在激发态具有高度的 ICT,对 PET 的倾向很小,这表现为发射的大红移锌2+配位而不增加荧光量子产率。缺乏电子的2a显示出相反的光物理结果,其中锌2+结合导致发射大大增强而没有显着的光谱偏移。电子结构对2a和2b中 ICT 和 PET 相对效率的影响以及锌2+- 使用实验和计算方法探测协调。这项研究表明,在异源配体中设计的各种光物理途径(例如ICT 和 PET)之间的微妙平衡敏感地依赖于配体的电子结构,即荧光团是富电子还是贫电子,它是否拥有供体——受体类型的结构,以及发生金属结合的位置。
