Chalcogenodiazolo[3,4-c]pyridine based donor–acceptor–donor polymers for green and near-infrared electrochromics

Thiadiazolo[3,4-c]pyridine and selenadiazolo[3,4-c]pyridine were employed as novel acceptors for rational design of donor-acceptor-type systems, yielding neutral green and near-infrared electrochromic polymers.
