A novel triarylamine-based conjugated polymer and its unusual light-emitting properties

Abstract

A new soluble triphenylamine-based conjugated polymer, poly[N-(4′-butylphenyl)imino(1,1′∶4′,1 ″-terphenyl-4′4″-ylene)], (PBPITP), has been synthesized, which emits blue photoluminescence (PL) with high absolute PL quantum efficiency (45 ± 3%) but exhibits red electroluminescence (red shifted by as much as 157 nm from the PL spectrum).
