A bichromic bipodal triphenylamine-based dye selected from the group consisting of:
- wherein Donor (D) is selected from a redox-active donor/chromophore (D) that is coupled through a p-spacer to an acceptor (A) capable of anchoring strongly to a semiconductor;
- wherein Anchor (A) is selected from acceptor/anchoring groups comprising electron-withdrawing carboxylic acid derivatives, conjugated to the p-spacer;
- and wherein p-spacer is selected from a p-conjugated spacer.
