Abstract

Abstract:

With diarylethene as one co-monomer, two backbone diarylethene polymers were synthesized through convenient routes. The solubility, photochromism and fatigue resistant property were studied. The two obtained polymers showed the reversible photochromic ability and excellent fatigue resistance. In the synthesis process of the two polymers, diarylethene and copolymer units were connected using rigid and flexible connections, respectively, and thus obtained diarylethene polymers with different spectral properties and molecular weight.

Key words: photochemistry, photochromism, polymers, synthesis, fatigue resistance

摘要：

以二芳基乙烯(二芳烯)为共聚单体之一,通过便捷的合成步骤,合成了两个骨架型二芳烯类聚合物,研究了其溶解性、光致变色能力及抗疲劳性等性质。所得到的两个二芳烯聚合物均具有可逆的光致变色能力和优秀的抗疲劳性。在两个聚合物合成过程中,二芳烯与共聚单元的连接分别采用刚性和柔性两种连接方式,从而得到了具有不同分子量及光谱性质的二芳烯聚合物。
