Abstract
We have synthesized an anthracene-based conjugated polymer, poly[(9,10-bis(oct-1-ynyl) anthracene)-alt-(5,6-bis(octyloxy)-4,7-bis(thiophen- 2-yl)benzo-[c][1,2,5]-thiadiazole)] (PANTBT), for application in organic photovoltaic devices. It exhibited a number average molecular weight of 14,300 g/mol and was fairly soluble in ch lilorinated organic solven ts due to flexible octynyl- and octy-loxy side chains on the P a nthracene and benzoth iadiazole moieties. P ANTBT showed absorption covering 300-660 nm. Through the bond alternation betwee ifn the electron-sufficient anthracene (and thiophene) and electron-deficient benzothiadiazole units, a band gap of PANTBT was decreased to 1.89 eV, showing a deep HOMO level of -5.31 eV. As a result, PANTBT exhibited promising photovoltaic properties with a PCE value of 1.90% (Voc = 0.77 V, Jsc = -6.50 mA/cm2, FF = 0.38) upon blending with PC71BM under AM 1.5G.
