摘要：
To demonstrate the effects of donor and acceptor units on the structure-property of electrochromism, we design and synthesize new block copolymers in this work. It is found that these units play key roles on the redox behavior, band gap, neutral state color and the electrochromic performance. Through changing the ratio between donor and acceptor units of copolymer, electrochromic performance and the response time of electrochromism are changed. More important, the mechanism and insightful understanding on electrochromic effects in block copolymers based devices are studied, and more information is provided for further electrochromic block copolymers design and devices fabrication.
