Efficient blue thermally activated delayed fluorescent emitters based on a boranaphtho[3,2,1-de]anthracene acceptor
A series of blue thermally activated delayed fluorescence (TADF) emitters have been developed by the combination of boranaphtho[3,2,1-de]anthracene (BO) acceptor (A) and sprio-acridine-fluorene donors (D). Different phenyl substitutions are induced for th
Synthesis of fluorenone derivatives through Pd-catalyzed dehydrogenative cyclization
Palladium-catalyzed dual C-H functionalization of benzophenones to form fluorenones by oxidative dehydrogenative cyclization is reported. This method provides a concise and effective route toward the synthesis of fluorenone derivatives, which shows outstanding functional group compatibility.
