Effect of arylamino-carbazole containing hole transport materials on the device performance and lifetime of OLED

We synthesized four hyper-conjugated aromatic hole transporting materials with different molecular geometry and energy levels by attaching arylamino moiety attached to the carbazole core. A brominated carbazole moiety reacted with an arylamino moiety using a Buchwald-Hartwig reaction. The characteristics of these hole transporting materials were investigated using TGA, DSC, UV–Vis and luminescence spectroscopy. The energy levels of all materials used in this study were estimated from cyclic voltammograms and absorption spectra. The hole transporting properties of the synthesized molecules were measured using single-carrier devices. All four hole transporting materials showed similar hole mobility. The effectiveness of hole transporting materials was compared by fabricating green-emitting organic light emitting diode (OLED) devices. It turned out that the device performances were critically dependent on the relative energy levels of the hole transporting layer and emission layer. However, the molecular geometry greatly influenced the device lifetime, determining thermally induced crystallization by the heat produced during device operation.

Aromatic amine compound containing carbazole group and organic light emitting diode thereof

The invention discloses an aromatic amine compound containing a carbazole group and an organic light emitting diode thereof, and relates to the technical field of organic photoelectric materials. Thearomatic amine compound structurally contains the specific carbazole group, on one hand, the carbazole group has a high triplet state energy level and a high hole mobility, on the other hand, the carbazole group has a relatively high redox potential value and has good stability under the condition of air or illumination, in addition, four hydrogen bonds of a phenyl group on a N site of the substituted carbazole group are replaced by four deuterium bonds, deuterium is non-toxic and non-radioactive and is 6-9 times more stable than a carbon-hydrogen bond, and therefore the compound with more stable property is obtained; in addition, by means of the carbazole and ortho-position connected biphenyl, conjugating of the structure is extended, and the hole transmission is facilitated; and the obtained aromatic amine compound is used as a hole-transport material or an optical extraction layer material in the organic light emitting diode and has the advantages of being high in efficiency, high in brightness and long in service life.

Nitrogenous heterocyclic ring derivative and organic light emitting device thereof

The invention provides a nitrogenous heterocyclic ring derivative and an organic light emitting device thereof, and relates to the technical field of organic photoelectric materials. On one hand, acridine is a macrocyclic conjugated system with a rigid plane structure, the rigid molecular skeleton of the macrocyclic conjugated system is favorable for improving the light and heat stability and thefluorescence quantum efficiency of the material, and meanwhile, the larger pi conjugated system can be used for improving the carrier injection and transmission property of the module. On the other hand, an acridine ring structure and a biphenyl structure generally form a p-pi large conjugation state through a nitrogen atom link, a large conjugate ring electron containing ability is enhanced, thenitrogen atom has a higher electron giving ability, a cavity can be more easily subjected to oxidation formation to display positive electricity, and therefore, the nitrogenous heterocyclic ring derivative has a high cavity migration rate. The organic light emitting device prepared by taking the structure as a cavity transmission material has the advantages of high light emitting efficiency and low driving voltage.
