Abstract

The synthesis, characterization and polymerization of two new electrochromic (EC) monomers based on 3, 4-alkylenedioxythiophene are reported. One is 3, 4-bis-(2, 2, 2-trifluoro-ethoxy)-thiophene which contains electron withdrawing group. Another is 6, 6-dimethy-6, 7-dihydro-5H-4, 8-dioxa-2-thia-6-sila-azulene which contains an electron donating group. Primary experiment results show that the new monomers have potential to form EC materials with new colors after polymerization. Color mixing of two EC polymers with blue and red color was studied. The principle of subtractive color mixing for achieving new color EC materials is also demonstrated.
