Claims25
A polymer comprising repeating units having the structure:
- wherein
- D1 is a first donor segment;
- D2 is a second donor segment, wherein D2 at each occurrence is selected from the group consisting of triphenylamine, N,N-diphenyl-2-thiophenamine, 9-phenylcarbazole, 9-(2′-thiophene)-carbazole, 4-phenyldithienopyrrole, 4-(2′-thiophene)-dithienopyrrole, 6,12-diphenylindolocarbazole, tetraphenylbiphenyldiamine, and tetraphenylbenzenediamine;
- A1 is an acceptor segment;
- B is a π-bridge moiety that conjugates D2 to A1;
- k is 1 or 2;
- and
- n is an integer from 2 to 2000.
