Largely Negative Energy Difference between the Singlet and Triplet Excited States and Ultrafast Delayed Fluorescence

Abstract Molecules exhibiting inversion of the lowest singlet and triplet excited states, referred to as inverted singlet–triplet (IST) molecules, can show a short delayed lifetime below 1 μs and are therefore promising candidates for next-generation emitters in organic light-emi...
