All solution-processed red organic light-emitting diode based on a new thermally cross-linked heteroleptic Ir(iii) complex

Abstract

A novel cross-linkable red iridium(iii) complex and electron transport material were designed and synthesized. The newly cross-linkable red Ir(iii) complex was successfully thermally cross-linked with a cross-linkable host in the emitting layer (EML). After cross-linking, the EML was not damaged by organic solvents.
