A design strategy for efficient MR-TADF emitters needs (i) avoiding aggregation by inducing steric hindrance at peripheral strategic positions, and (ii) combining lateral groups of higher donor character as compared to the central core.
A series of donor–acceptor alternating copolymers with Mn ≤ 12,000 g mol–1 and moderate polydispersity (Đ = 1.5–2.5) were synthesized via RAFT copolymerization styrene-based donor monomers maleimide-type acceptor in the presence S-dodecyl-S′-(α,α′-dimethyl-α″-acetic acid)trithiocarbonate as a chain transfer agent. It was shown that characterized by high thermal stability (Td5 375–465 °C), most them exhibited exciplex emission through-space charge-transfer (TSCT) mechanism displayed...
The multifunctional materials for application in organic light-emitting devices (OLEDs) based on a single structural motif are very desired but quite rare species. Such structures allow simplifying the chemical variety within OLED heterostructures and thus reducing their cost, manufacturing time, logistic efforts. In this paper, we report 9-(2,3,5,6-tetrafluoro-4-vinylphenyl)carbazole molecule (Cz4FS) utilized as fluorescent emitter, host material quantum dot OLEDs (QLEDs), acceptor part of...
Abstract Multiresonance thermally activated delayed fluorescence (MR‐TADF) emitters with high color purity in virtue of their inherent narrowband emission have received great interest organic light‐emitting diodes (OLEDs). However, it remains a big challenge to develop the ultrapure blue MR‐TADF efficiency. In this work, novel “dual‐MR‐core” strategy is proposed by connecting two parent N‐B‐O‐skeletons non‐conjugate 9‐position substituted fluorene linkages for efficient deep‐blue emitters,...
Photoinduced radical and step-growth polymerizations of carbazole functional styrene (vinyl phenyl carbazole, VPC) by sequential one-pot strategies have been investigated. The obtained polymers were characterized FTIR, 1H-NMR, GPC, UV–Vis, PL, CV, BET analyses. theoretical charge distribution HOMO–LUMO calculation DFT well-matched with those from optical electrochemical measurements. In the approach, visible light-induced free-radical photopolymerization VPC using bisacyl phosphineoxide...
