The invention provides three-coordinated organoboron compounds that are useful for photoluminescence and electroluminescence. Compounds of the invention include light emitters, preferably emitting intense blue light, electron transporters, hole transporters and hole injectors. A particularly preferred such compound is p-(1-naphthylphenylamino)-4,4′-biphenyldimesitylborane (BNPB), which demonstrates all of these properties. The invention further provides methods of synthesizing such three-coordinated boron compounds, methods of producing photoluminescence and electroluminescence, methods for charge transports, methods for hole injection, methods of applying the compounds in thin films, and uses of the compounds of the invention in luminescent probes, and electroluminescent displays.

An efficient, highly regioselective, and scalable ruthenium-catalyzed o-aryl C–H mono-cyanation of N-aryl-7-azaindoles to form N-(2-cyanoaryl)-7-azaindoles has been developed through N-directed ortho C–H activation using N-cyano-N-phenyl-p-toluenesulfonamide as cyanating reagent in the presence of AgOTf and NaOAc in DCE. A range of substrates has furnished cyanated azaindoles in good to excellent yields

aminocarbonylation of N-(hetero)aryl-7-azaindoles with isocyanates is described. The excellent site selectivity at the ortho-position within the N-(hetero)aryl ring was observed to provide ortho-amidated N-(hetero)aryl-7-azaindoles under the mildreactionconditions. The resulting 7-azaindole derivatives can be readily transformed into 7-azaindoles containing carboxylic acid and alkyl amine functional groups
