Green-emitting dendritic alkynylgold() complexes with excellent film morphologies for applications in solution-processable organic light-emitting devices

Bipolar cyclometalated dendritic alkynylgold( iii ) complexes that exhibit excellent film morphologies in solid-state thin films have been designed and synthesized. Together with their high luminescence quantum yields, high performance solution-processable organic light-emitting devices have been re...

Description
Summary:Bipolar cyclometalated dendritic alkynylgold( iii ) complexes that exhibit excellent film morphologies in solid-state thin films have been designed and synthesized. Together with their high luminescence quantum yields, high performance solution-processable organic light-emitting devices have been realized, maintaining high external quantum efficiencies of >12% for dendrimers up to the second generation. Bipolar dendritic alkynylgold( iii ) complexes that exhibit excellent film morphologies in solid-state thin films have been designed and synthesized. Solution-processable OLEDs with EQEs >14.5% have been achieved.
