缺电子端基(EGs)对于非富勒烯小分子受体(NF-SMA)调节其吸收,能级和结晶特性非常重要。在这里,我们通过将甲基单元添加到2-(6-oxo-5,6-dihydro-4 H -cyclopenta [ c ] thiophen)中,设计并合成了三种SMA,即BTTIC-0M,BTTIC-2M和BTTIC-4M。-4-亚丙基)丙二腈(CPTCN)。甲基,具有轻微的给电子能力,可显着提高LUMO能级,但不会严重影响基于CPTCN的SMA的带隙,从而有助于减少能量损失(E损失)。)。对供体-受体(DA)复合物的深入动态理论模拟表明,可以通过连续增加SMAs端基上的甲基来微调激子键能(BE)。甲基取代的EG降低了驱动力,还增强了电荷传输(CT)态激子的BE,导致激子解离效率降低。但是,我们发现一种甲基官能化的CPTCN使基于PBDB-T:BTTIC-2M的有机太阳能电池(OSC)的功率转换效率(PCE)高达13

The disclosure relates to thiophene-based ditin compounds and methods of making and using such compounds. The disclosed compounds are novel structures having organotin groups on a conjugated aryl group spaced from and adjacent to a fused thiophene moiety. The formation of trialkyl tin groups spaced away from the fused thiophene moieties is advantageous in that it allows for novel polymerization via Stille coupling.
