A series of organic dipolarcompoundscontaining a donor (D), a bridge (B), and an acceptor (A), forming a D–B–A type of dyads, were synthesized by convenient methods and were utilized successfully on dye-sensitizedsolarcells. The central bridges were made of three linearly connected arylene groups, i.e., phenylenes or thiophenylenes. The donor groups were aromatic amines, i.e., either a diphenylamine
