Efficient up-conversion of triplet excitons into a singlet state and its application for organic light emitting diodes

A material possessing a very small energy gap between its singlet and triplet excited states, Δ E 1 − 3 , which allows efficient up-conversion of triplet excitons into a singlet state and leads to efficient thermally activated delayed fluorescence (TADF), is reported. The compound, 2-biphenyl-4,6-bi...
