We report a molecular engineering study on optical, structural and electrical properties of seven silole derivates aimed at enhancing the charge carrier balance in single-layer devices. By functionalizing two hole-transporting groups, dipyridylamine and anthracene, on the silole ring, we have investigated the influence of both substituents on the hole current. We have concluded that in contrast to dipyridylamine groups, anthracene groups decrease the charge carrier balance since the latter groups not only increase the hole current but also electron contribution. Mixing these hole-transporting groups and doubling their number lead to a novel silole becoming a very efficient emissive layer exhibiting threshold voltage below 3 V and luminous efficiency Le = 0.8 cd A-1 at 7 V.

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.

Eight novel three-coordinate boron compounds with the general formula BAr2L, in which Ar is mesityl and L is a 7-azaindolyl- or a 2,2′-dipyridylamino-functionalized aryl or thienyl ligand, have been synthesized by Suzuki coupling, Ullmann conde
