摘要: A new two-dimensional tetrathienyl-TBDT (TBDT-4T) was synthesized by employing palladium-catalyzed C-H benzannulation between an iodobiaryl and 1,2-dithienylacetylene. The stannylated TBDT-4T was copolymerized with di(thiophenyl)difluorobenzothiadiazole (FBT) and fluorothienothiophene (FTT) monomers to yield PTBDT-FBT and PTBDT-FTT, which showed high decomposition temperatures (421 and 408 degrees C) and deep-lying HOMO levels (-5.80 and -5.84 eV). The inverted solar cell device using PTBDT-FBT:PC71BM (1: 1 in wt%) blend showed a power conversion efficiency (PCE) of 4.16%, while the device using PTBDT-FTT:PC71BM (1: 2 in wt%) blend showed a PCE of 3.98%.
