Abstract:The impact of the connection modes between donor (D) and acceptor (A) on the luminescence properties is revealed for organic D‐A‐D emitters based on triphenylamine (TPA) and 9,10‐phenanthroquinone (PAQ). When TPA and PAQ are linked via a single bond, the emitters exhibit small energy difference between the lowest singlet and triplet excited states (∆EST) due to the separated highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) distributions, thus featuring thermally activate… Show more
“…[18][19][20][21][22][23][24] At the same time, many theoretical research groups have performed a lot of research to detect the inner RTP mechanisms and design new efficient RTP molecules. [25][26][27][28][29][30][31][32] Ma et al revealed the dual RTP emission source based on first-principles calculations, and the T 1 state and the upper-lying triplet excited state (T 2 ) were responsible for the dual RTP mechanism. 33 Shuai and Peng et al used molecular dynamics simulations, and the combined quantum mechanics and molecular mechanics (QM/MM) coupled with thermal vibration correlation function (TVCF) theory to propose a mechanism for the induction of RTP by intermolecular electrostatic interactions at the molecular level.…”
Stimulus-responsive organic room temperature phosphorescence (RTP) materials with long lifetimes, high efficiencies and tunable emission properties have broad applications. However, the amounts and species of efficient RTP materials are far...

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
