摘要

Direct arylation methods have been used to polymerize thienylmethylene oxindoles(TEIs)and 3,3-bis[[(2-ethylhexyl)oxy]methyl]-3,4-dihydro-2H-thieno-[3,4-b][1,4]dioxepin(ProDOT)for new donor-acceptor conjugated polymers.The polymers exhibited blue hues in neutral-state with distinct color-to-transmissive reversible electrochromic switching under applied potentials from 0 V to+1.5 V,and showed high coloration efficiencies(436-438 cm2.C-1)in near-infrared regions with high switching speeds around 1-2 s under ambient conditions.
