straightforward synthesis toward two conjugated alternating copolymers consisting of 2,7-linked carbazole donor (2,7-Cz) and ladderized pentaphenylene with diketone bridge (LPPK) acceptor chromophores is reported: the copolymers differ by the repeat unit ratio between the 2,7-Cz and LPPK units within the backbone; energy and charge transfer properties and supramolecular organizations of donor-acceptor moieties
据报道,可以直接合成两种共轭交替共聚物,其中包括2,7-连接的咔唑供体(2,7-Cz)和带有二酮桥(LPPK)受体的梯化五苯撑生色团:共聚物之间的重复单元比有所不同,2骨干内的7-Cz和LPPK单元;已经通过光谱学和二维广角X射线散射(2D-WAXS)研究了这些共聚物中供体-受体部分的能量和电荷转移性质以及超分子组织。诸如固态中的有效能量和电荷转移以及pi堆积特性等初步结果表明,该共聚物潜在地可用于光伏器件。
