DTDCPB) were strategically designed and convergently synthesized as donor materials for small-molecule organic solar cells. These compounds possess a donor-acceptor-acceptor molecular architecture, in which various electron-donating moieties are connected to an electron-withdrawing dicyanovinylene moiety through another electron-accepting 2,1,3-benzothiadiazole block. The molecular structures and crystal
三种新的定制分子(DPDCTB、DPDCPB 和 DTDCPB)经过战略性设计和聚合合成,作为小分子有机太阳能电池的供体材料。这些化合物具有供体-受体-受体分子结构,其中各种供电子部分通过另一个受电子 2,1,3-苯并噻二唑嵌段连接到吸电子二氰基亚乙烯基部分。DTDCPB 和先前报道的 DTDCTB 的分子结构和晶体堆积通过单晶 X 射线晶体学表征。彻底研究了这一系列供体分子的光物理和电化学性质以及能级,提供了清晰的结构-性质关系。
