Enhanced NIR Electrochromic Properties of Corannulene-(triphenylamine)₅ and EDOT-Derived Polymers via Electrochemical Layer-by-Layer Polymerization Compared to Copolymerization.

ABSTRACT: This study explores the electrochemical and electrochromic properties of polymers derived from corannulene-(triphenylamine)₅ (CT) and 3,4-ethylenedioxythiophene (EDOT) through electrochemical copolymerization and layer-by-layer polymerization techniques. To address the high oxidation potential of EDOT, an EDOT dimer (BiEDOT) was synthesized, which facilitated successful copolymerization with CT. The resulting copolymer films, P10 and P8, exhibit enhanced near-infrared (NIR) electrochromic properties, with P8 showing better performance in NIR absorption. Comparative analysis with layer-by-layer films (PLs) reveals distinct electrochemical behaviors with PLs demonstrating higher NIR and lower visible absorbance with improved optical properties. Among PLs, PL6 exhibits the best NIR
