  A method of thermocleaving a thermocleavable polymer layer which is in thermal contact with a heat sensitive component that is not tolerant of the temperature required for thermocleavage of the thermocleavable polymer layer, in which the thermocleavable polymer layer is illuminated with a light source having a wavelength range more strongly absorbed by the thermocleavable polymer and substantially less strongly absorbed by the heat sensitive component, such that the thermocleavable polymer layer reaches a temperature sufficient to cause thermocleavage of the polymer without causing detrimental heating to the heat sensitive component. Further provided is apparatus for carrying out the above method.

  一种热解可分解聚合物层的方法，该层与热敏感元件保持热接触，但热敏感元件不能耐受热解所需的温度，其中，热解可分解聚合物层被照射具有更强吸收热解可分解聚合物的波长范围的光源，且该波长范围被热敏感元件吸收的强度显著较小，以使热解可分解聚合物层达到足够的温度，从而引起聚合物的热解，而不会对热敏感元件造成有害加热。此外还提供了用于执行上述方法的装置。

  Three green EC materials based on thiophene, and a green EC material based on 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 to selectively change to a green color state, and can be polymerized to achieve a green EC polymer.
