摘要：Three green EC materials based on thiophene, and a green EC material basedon pyrazine are disclosed. A first thiophene derivative (2,3-Di-thiophen-2-yl-thieno[3,4-b]pyrazine), which was previously investigated as a nonlinear optical material, is here
disclosed for its use as an EC material, and for its incorporation into an EC device.Synthesis of two new thiophene derivatives (2,5-di(thien-2-yl)-3,4-di(2,2,2-trifluoro-ethoxy)-thiophene and 2,5-(2,3-dihydro-thieno[3,4-b][1,4]dioxin-5-yl)-3,4-di(2,2,2-trifluoro-ethoxy)-thiophene), and a new pyrazine derivative (2,3-dibenzyl-5,7-di(thien-2-yl)thieno[3,4-b]pyrazine) are also disclosed, since these materials are all able toselectively change to a green color state, and can be polymerized to achieve a green ECpolymer.
