An In-Depth Quantum Chemical Investigation of INVEST TADF Dyes

open access: yesThe Journal of Physical Chemistry Letters
The design of organic emitters with inverted singlet-triplet (INVEST) gaps presents a promising route to enhance triplet harvesting in optoelectronic applications, yet reliable descriptors for predicting this phenomenon remain scarce. Here, we introduce a wave function-based descriptor, Qat, derived from the transition density matrix, to quantify the ...
