Synthesis and photochemical properties of 3,6-di-tert-butyl-9H-carbazole derivatives
摘要:
Method of synthesis has been developed for a series of 3,6-di-tert-butyl-9H-carbazole derivatives and their photochemical properties have been investigated. The dependence of the Steglich esterification reaction on the nature of the catalyst was studied. The synthesized compounds show fluorescent emission in the range 400-600 nm with a high quantum yield.
Dinuclear Pt(III) complexes were commonly reported to have short-lived lowest-lying triplet states, resulting in extremely weak or no photoluminescence. To overcome this obstacle, a new series of dinuclear Pt(III) complexes, named as Pt2a-Pt2c, were strategically designed and synthesized using donor (D)-acceptor (A)-type oxadiazole-thiol chelates as bridging ligands. These dinuclear Pt(III) complexes

Spirofluorene‐cored bis(difluoroboron β‐diketonate) complexes bearing terminalcarbazoles (CbzBSF) and tert‐butylcarbazoles (TCbzBSF) have been synthesized. It was found that only TCbzBSF could form organogels in cyclohexane and methylcyclohexane, suggesting that tert‐butylcarbazole was essential for its organogelation directed by weak π–π interactions.
