Dendrimers containing luminescent gold (III) compounds for organic light-emitting devices and their preparation

摘要

A novel class of saturated or conjugated dendrimers containing at least one strong σ-donating group coordinated to cyclometalated tridentate gold(III) compounds having the chemical structure depicted by generic formula:; wherein:(a) [Au] is a cyclometalated tridentate gold(III) group;(b) Unit A is a σ-donating chemical group;(c) Unit B is a central part of the dendrons comprising a branch point of component dendrimers;(d) Unit C is optional surface groups or dendrons of the dendrimers;(e) n=0 or 1.
