Electrochromic polymers called poly(3,4‐dihydro‐3,3‐bis ((naphthalen‐1‐yl)methyl)‐2H‐thieno[3,4‐b][1,4]dioxepine) (PProDOT‐Np2), poly(3,3‐dibenzyl‐3,4‐dihydro‐2H‐selenopheno[3,4‐b][1,4]dioxepine), and poly(3,3‐dibenzyl‐3,4‐dihydro‐2H‐thieno[3,4‐b][1,4]dioxepine) were synthesized electrochemically and the effect of substituents and heteroatoms on the electrochromic properties were investigated for the
电致变色聚合物称为聚(3,4-二氢-3,3-二((萘-1-基)甲基)-2H-噻吩并[3,4-b] [1,4]二氧杂环庚烷)(PProDOT-Np 2) ,聚(3,3-二苄基-3,4-二氢-2H-硒代苯[3,4-b] [1,4]二氧哌啶)和聚(3,3-二苄基-3,4-二氢-2H-噻吩并[3,4-b] [1,4]-二氧杂环丁烷是通过电化学方法合成的,并研究了类似体系中取代基和杂原子对电致变色性能的影响。当被中和时,所有聚合物都显示出从有色状态到变色的电致变色现象。尽管体积越来越大(PProDOT-Np 2)导致较低的着色效率(CE)以及较低的光学对比度,S原子被Se原子取代导致带隙较低的聚合物具有比其噻吩类似物更高的CE。©2011 Wiley Periodicals,Inc.
