Synthesis of novel arylamine containing perfluorocyclobutane and its electrochromic properties†
Abstract
A new electrochromic oligomer based on an arylamine compound containing a perfluorocyclobutane (PFCB) ring has been synthesized via 2 + 2 cyclodimerization. A new N,N,N′,N′-tetraphenyl-biphenyl-4,4′-diamine (
