Abstract

A new star-shaped small molecule BDPP-1 based on 1,3,5-triethynylbenzene as a core and diketopyrrolopyrrole (DPP) as rigid arms have been successfully designed and synthesized. The thermal stability, photophysical and electrochemical properties were explored. The synthesized star-shaped small molecule BDPP-1 exhibited excellent solubility, high thermal stability, broad and strong absorption, narrow band gap and appropriate molecular levels. Moreover, the photoinduced charge separation process between the synthesized donor and acceptor PCBM was evaluated by the fluorescence quenching experiment, revealing that the donor material BDPP-1 possessed efficient photoinduced charge separation performance. These detailed investigations on the structure-property relationship of the novel star-shaped molecule revealed that BDPP-1 is a prospective candidate as a donor material for organic photovoltaic materials.

摘要

一种以1,3,5-三乙炔基苯为核心、二酮吡咯并吡咯（DPP）为刚性臂的新型星形小分子BDPP-1已成功设计并合成。对其热稳定性、光物理和电化学性质进行了探索。合成的星形小分子BDPP-1表现出优异的溶解性、高热稳定性、宽且强的吸收、窄带隙和合适的分子能级。此外，通过荧光猝灭实验评估了合成的供体与受体PCBM之间的光诱导电荷分离过程，结果表明供体材料BDPP-1具有高效的光诱导电荷分离性能。对这种新型星形分子结构-性能关系的这些详细研究表明，BDPP-1是有机光伏材料供体材料的一个有前景的候选物。
