将含有双冠醚结构的乙烯基单体与几种乙烯基单体进行共聚，得到侧链上带有光致变色冠醚结构的聚合物。聚合物冠醚孔雀绿衍生物对K+和Cs+具有比Li+和Na+更强的金属离子络合能力，离子选择性与相应的单体类似物有很大的不同。它们的冠醚部分的金属离子络合作用对孔雀石绿的光致变色性有很大的影响。光诱导阳离子形式的脱色反应也受聚合物在溶液中的流变性控制。
Vinyl monomers containing a bis-crowned Malachite Green leuconitrile moiety were copolymerized with several vinyl monomers to afford polymers carrying the photochromic crown ether moiety at the side chain. The polymeric crowned Malachite Green derivatives were found to have the higher metal ion complexing ability toward K + and Cs + than Li + and Na + , the ion selectivity being quite different from their corresponding monomeric analogues. The photochromism of their Malachite Green moiety was affected considerably by the metal ion complexation of their crown ether moiety. The decoloration reaction of the photoinduced cationic form was also governed by the polymer rheology in solution.
