Inverted SingletTriplet Gaps and Their Relevance to Thermally Activated Delayed Fluorescence
The basic design principle for emitters exhibiting thermally activated delayed fluorescence (TADF) is the minimization of the singlet-triplet gap. While typically this gap is positive, a possible inversion of states has been proposed as a pathway to improve the efficiency of organic light-emitting diodes. Despite the efforts to design such emitters, there are very few reports indicating that it is at all possible. We analyze the problem of the gap inversion from the perspective of thedoi:10.1021/acs.jpclett.9b02333.s001 fatcat:idkwvqu3mrdc5k5awac44mp7iy
