摘要：

Concentration quenching of thermally activated delayed fluorescence is found to be dominated by electron-exchange interactions, as described by the Dexter energy-transfer model. Owing to the short-range nature of the electronexchange interactions, even a small modulation in the molecular geometric structure drastically affects the concentration- quenching, leading to enhanced solid-state photoluminescence and electroluminescence quantum efficiencies.
