Two polymers, poly [4-(5-(2,5-bis((2-hexyldecyl)oxy)phenyl)thiophen-2-yl)-5,6-difluoro-2-octyl-7-(thiophen-2-yl)-2H-benzo[d][1,2,3]triazole](PPDTBTz-2HD) and poly [4-(5-(2,5-bis((5-hexyltridecyl)oxy)phenyl)thiophen-2-yl)-5,6-difluoro-2-methyl-7-(thiophen-2-yl)-2H-benzo[d][1,2,3]triazole](PPDTBTz-5HD), which had different branch position of alkyl chain on the benzene unit, were designed and synthesized. Two polymers were synthesized by Stille-coupling polymerization using anhydrous chlorobenzene with microwave reactor. To check the properties of polymers, we measured UV-vis spectroscopy and cyclic voltammetry (CV) and gel permeation chromatography (GPC). To investigate photovoltaic performances, we fabricated and optimized a inverted arrangement with [ITO/ZnO/polymer:PC71BM or ITIC)/MoO3/Ag]. |
