简单介绍


ossila材料t-DABNA  的详细介绍

t-DABNA emitter, together with 9,10-bis(1-naphtyl)anthracene (α-ADN) host to harvest only singlet excitons, showed high external quantum efficiency of 7.6% as fluorescent emitters and lifetime longer than that of a conventional pyrene derived blue emitter.

Boron-based multiresonance MR-TADF emitters show great application potential in great color purity with narrowband emission and superior photoluminescence quantum yield (PLQY) coupled with the small singlet–triplet energy splitting.

A planar structure, v-DABNA, is also available in sublimed grade purity.
