简单介绍


ossila材料TBRb  的详细介绍

A family member of tetracene, 2,8-Di-tert-butyl-5,11-bis(4-tert-butylphenyl)-6,12-diphenyltetracene (TBRb) has been widely used as a yellow dopant material in TADF-OLEDs. It is popular because of its bipolar characteristics.

The greater hindrance introduced by four tetra-tert-butyl bulky steric groups (attached to the benzene rings of rubrene) is believed to reduce the chances of concentration-quenching by effectively preventing inter-molecular aggregation of the dopant molecules. In return, this can improve device performance (e.g. in terms of external quantum efficiencies, overall power efficiencies, and lifetime).
