Abstract

A series of star-shaped donor-acceptor oligomers having alkyldicyanovinyl fragments as electron-withdrawing groups, 2,2′-bithiophene as a conjugated π-bridge and either triphenylamine or its modified analogs (9-phenyl-9H-carbazole derivatives or tris(2-methoxyphenyl)amine as electron-donating cores was designed, synthesized and investigated. Variation of the chemical nature of the donor core allowed elucidating the structure-properties relationships for their solubility, absorption spectra, electrochemistry, phase behavior as well as photovoltaic performance in bulk heterojunction organic solar cells as donor materials in their mixtures with PC₇₀BM. The star-shaped molecules based on triphenylamine and tris(2-methoxyphenyl)amine cores have reduced bandgaps, which leads to more efficient absorption of the sun light and better photovoltaic performance.
