A series of organic dipolar compounds containing 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-sensitized solar cells. The central bridges were made of three linearly connected arylene groups, ie, phenylenes or thiophenylenes. The donor groups were aromatic amines, ie, either a diphenylamine or a naphthylphenylamine group. The ...
