Yellow-to-transmissive electrochromic poly(dibenzothiophene/dibenzofuran-bithiophene)

Electrochromic technologies require electrochromic π-conjugated polymers to reversibly transition between highly transmissive and broadly absorbing achromatic states, fast response time, and high kinetic stability. In this work, yellow-to-transmissive electrochromic poly(dibenzothiophene/dibenzofuran-bithiophene) (PDBT-2Th and PDBF-2Th) were prepared by electropolymerization of monomers DBT-2Th and DBF-2Th. Attaching bithiophene at both the 2...
