Abstract

Abstract:

The water-soluble polythiophene electroyte, poly[3-(1'-propyloxy-3'-acid sulfonate) thiophene](PTH-n₃-SO₃H), was prepared. Its application as electroyte in organic electrochromic devices was investigated. 5,5"'-diformyl-2,2': 5',2": 5",2"'-tetrathiophene(4T-2CHO) and 5,5"'-dicyane-2,2': 5',2": 5",2"'-tetrathiophene(4T-2CN) films showed reversible, clear color changes in PTH-n₃-SO₃H aqueous solution. When the voltage were applied between the ITO working electrode and the platinum wire counter electrode, the 4T-2CHO film showed reversible, clear color changes from yellow to blue-green, while the 4T-2CN film showed reversible, clear color changes from light yellow to blue. The results also indicate that PTH-n₃-SO₃H can be used as electroyte in organic electrochromic devices.
