Nearly 100％exciton utilization in highly efficient red OLEDs based on dibenzothioxanthone acceptor
文献摘要：
Improving the utilization of excitons has always been an important topic for the development of elec-troluminescence devices.In this work,we designed and synthesized three red TADF emitters TPA-DBT12,TPA-DBT3 and DTPA-DBT by employing dibenzothioxanthone(DBT)acceptor framework to stabilize the locally excited triplet state to participate in the reverse intersystem crossing(RISC)process.The fast RISC process and singlet radiation decay process gave rise to evidently enhanced exciton utilization.All of the red OLEDs based on these materials showed maximum EQE over 11％and high exciton utilization close to 100％.This work not only extend the acceptor framework for red materials but also provide a new per-spective for the design of highly efficient red TADF materials with 100％exciton utilization by managing locally excited triplet state.
