In this study, we designed and synthesized three series of blue emitting homoleptic iridium(III) phosphors bearing 4-cyano-3-methyl-1-phenyl-6-(trifluoromethyl)-benzo[d]imidazol-2-ylidene (mfcp), 5-cyano-1-methyl-3-phenyl-6-(trifluoromethyl)-benzo[d]imidazol-2-ylidene (ofcp), 1-(3-(tert-butyl)phenyl)-6-cyano-3-methyl-4-(trifluoromethyl)-benzo[d]imidazol-2-ylidene (5-mfcp) cyclometalates, respectively. These iridium complexes exhibit intense phosphorescence in the high energy region 435-513...
We studied a family of coordination compounds with short intramolecular spatial separation between an organic chromophore and metal centre. The specific geometry was realized by means anthracene‐functionalized tertiary aryl phosphanes. Their silver gold complexes (1, 2) operate as conventional fluorophores, photophysical behavior defined anthracene‐localized allowed transitions. In contrast, bichromophoric species, containing phenyl bipyridine‐ (3, 5, 6, 8) or terpyridine‐ (4, 7) derived...

Singlet fission (SF) holds great promise for current photovoltaic technologies, where tetracenes, with their relatively high triplet energies, play a major role application in silicon-based solar cells. However, the SF efficiencies tetracene dimers are low due to unfavorable energetics of singlet and energy levels. In solid state, exhibits yields formation through SF, raising interest about underlying mechanisms. To address this discrepancy, we designed prepared novel molecular system based...

Abstract The new host materials are reported to boost the multiple resonance‐induced thermally activated delayed fluorescence (MR‐TADF) based pure deep‐blue organic light emitting diodes (OLEDs) toward further shortening emission full width at half maximum (FWHM). Based on an unusual asymmetric design concept, two compounds Bz2cb and Bz2cbz synthesized. Despite possessing a compact rigid molecular packing in crystal, shows amorphous morphology via vapor deposition, as confirmed by...
