5, 5″‐Bis{4‐[bis(4‐methylphenyl)amino]phenyl}2, 2′:5′, 2″‐terthiophene and 5, 5‴‐bis{4‐[Bis(4‐methylphenyl)amino]phenyl}2, 2′:5′, 2″:5″, 2‴‐quaterthiophene as a Novel Family of Amorphous Molecular Materials

Abstract

A novel family of photo‐and electroactive amorphous molecular materials containing an oligothiophene moiety linked to two triphenylamine moieties has been designed and synthesized (see Figure). Their glass‐forming properties, morphological changes, and molecualr and solid‐state properties are described. They are reported to exhibit multiredox behavior on electrochemical oxidation. magnified image
