AIEE-Active and Electrochromic Bifunctional Polymer and a Device Composed thereof Synchronously Achieve Electrochemical Fluorescence Switching and Electrochromic Switching
A novel
alternating polymer, ProDOT-TPE, with aggregation-enhanced fluorescent
emission and electrochromic properties based on thiophene and tetraphenylethene
derivatives was designed, synthesized, and characterized. The polymer
displays weak photoluminescence in tetrahydrofuran, but its corresponding
film prepared by spray-coating exhibits yellow-green fluorescent light
at 540 nm. The color of the polymer film could be switched from bright
yellow to navy blue by applying a relatively low voltage. An electrochromic
device (ECD) of the polymer was fabricated that differs from common
ECDs because both its color and fluorescent state could be synchronously
switched by an applied voltage, making the polymer a unique candidate
for electrochemical fluorescence and electrochromic applications
