ORGANIC COMPOUNDS, ORGANIC LIGHT EMITTING DIODE AND ORGNIC LIGHT EMITTING DEVICE HAVING THE COMPOUNDS

The present invention relates to an organic compound having an aromatic ring linked to a bipyridine moiety directly or through a linker in the bipyridine moiety. According to the present invention, the organic compound has a bipyridine moiety having excellent n-type characteristics, thereby minimizing exciton quenching by an interaction between a triplet exciton of a dopant and a peripheral hole-polarone. Accordingly, it is possible to prevent the lifespan of a light emitting diode element from being reduced by electro-oxidation and photo-oxidation. In addition, in the organic compound of the present invention, at least one of the bipyridine moiety and/or the aromatic ring is substituted with a cyano group, so that an energy band gap and an excited triplet energy level (T_1) are not deteriorated and luminous efficiency is thus improved. Therefore, the organic compound of the present invention can be used as a host of a light emitting material layer by being used with, for example, a delay fluorescent dopant emitting blue light. The organic compound of the present invention can be used in an organic light emitting diode and an organic light emitting device with improved luminous efficiency and especially element lifespan.COPYRIGHT KIPO 2019

Bipolar host materials for high-efficiency blue phosphorescent and delayed-fluorescence OLEDs

A series of small molecular isomers, namely o-CzCN, m-CzCN, and p-CzCN, are developed for use as bipolar hosts in blue phosphorescent and fluorescent organic light-emitting diodes (OLEDs). Cyano (CN) substituted phenyl is selected as the n-type unit and N-phenyl-substituted carbazole as the p-type unit. By adjusting the ortho-, meta-, and para-linking styles of the functional units, the physical parameters are regularly tuned to a large extent. The study of complete spatial separation of frontier molecular orbitals and single-carrier devices confirm the bipolar feature. Blue phosphorescent and thermally activated delayed fluorescence (TADF) OLEDs were fabricated using iridium(iii)bis(4,6-(difluorophenyl)pyridinato-N,C2′)picolinate (FIrpic) and 1,2-bis(carbazol-9-yl)-4,5-dicyanobenzene (2CzPN) as doped emitters. A maximum current efficiency of 46.81 cd A-1 and an external quantum efficiency of 23.14% were achieved for the phosphorescent OLED with the m-CzCN host. Furthermore, high efficiencies of 29.23 cd A-1 and 14.98% were obtained for the 2CzPN based blue TADF device with the o-CzCN host, which are higher than the best literature value of 13.6% for 2CzPN devices. Both m-CzCN and o-CzCN always perform better than p-CzCN. The influence of the chemical structures on their properties and performance is interpreted for these CN-decorated host materials.
