Abstract

Abstract:

Thermally activated delayed fluorescence polymers can achieve 100% internal quantum efficiency by utilizing triplet excitons through enhanced reverse intersystem crossing process from the lowest triplet state to singlet state, thereby representing a promising approach toward low-cost and high-effiicnecy light-emitting polymers. Recently, great progress has been made on the material design and device performance of thermally activated delayed fluorescence polymers. This review is aimed to summarize the research progresses on thermally activated delayed fluorescence polymers, with the focus on the molecular design, photophysical characteristic and device performance of mainchain- and sidechain-type thermally activated delayed fluorescence polymers as well as thermally activated delayed fluorescence dendrimers. Finally, the perspectives and the key challenges on developing thermally activated delayed fluorescence polymers are also discussed.

Key words: thermally activated delayed fluorescence, organic light-emitting diodes, light-emitting polymer, solution process
