A series of carbazole‐dendronized tris(2,4,6‐trichlorophenyl)methyl (TTM) radicals have been synthesized. The photophysical properties of dendronized radicals up to the fourth generation were compared systematically to understand how structure–property relationships evolve with generation. The photoluminescence quantum yield (PLQY) was found to increase with the increasing generation, and the fourth generation (G4TTM) in cyclohexane solution showed a PLQY as high as 63 % at a wavelength of 627 nm (in the deep‐red region) from the doublet state. The dendron modification strategy also showed a blue‐shift of the emission on increasing the generation number, and the photostability was also increased compared to the bare TTM radical.
Carbazole dendrimers with benzophenone core and bulky terminal substituents were synthesized, and thermally-activated delayed fluorescence (TADF) property was investigated. The adamantane (Ad) substituted dendrimer showed green TADF emission with PLQY...
Four types of carbazole dendrimers were applied as modification molecules of Au surface to improve carbon dioxide electroreduction. The reduction properties depended on the molecular structures: the highest activity selectivity...

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.
