Abstract

Abstract: A thiaazulenic quinone TAQ was synthesized and its optical and redox properties were investigated. The deep blue‐colored compound is readily and reversibly reduced to the colorless anionic state. Electrochromic films were prepared and showed reversible switching behavior for the anodically coloring and NIR electrochromic material. Abstract : True blue : A thiophene‐based bisquinone is a functional electrochrome that switches from blue in the neutral state to colorless in the reduced state.
