The invention belongs to the technical field of organic materials, and provides a nitrogen-containing compound, an electronic element and an electronic device. The structure of the nitrogen-containingcompound is shown as a formula 1, wherein X1, X2 and X3 are respectively and independently selected from C or N, and at least one of X1, X2 and X3 is N; wherein R1, R2 and R3 are respectively and independently selected from hydrogen or a group shown in a chemical formula 1-1, and only one of R1, R2 and R3 is a group shown in a chemical formula 1-1. The nitrogen-containing compound can improve theperformance of an electronic component.
The invention provides a compound shown as a formula I, a photoelectric conversion device and an electronic device, and belongs to the technical field of organic materials. The compound can reduce theworking voltage of the photoelectric conversion device, improve the luminous efficiency of the photoelectric conversion device and prolong the service life of the device.
To provide a light-emitting material containing a compound having a high excitation triplet level, particularly a host material of a light emitting layer, as a material for an organic electroluminescent device with high efficiency, and also to provide an organic electroluminescent device with high efficiency and high luminance by using the material. A light-emitting material containing a compound having a carbazole ring structure represented by the following general formula (1), and an organic electroluminescent device containing a pair of electrodes and one layer or plural layers including at least a light emitting layer intervening between the electrodes, the light emitting layer containing as a constitutional material thereof the light-emitting material.
Provided are a heterocyclic compound and an organic light-emitting device including the same. The heterocyclic compound includes a fluoro-containing cyclic group. The heterocyclic compound does not include a carbazole group, a dibenzofuran group, a dibenzothiophene group, and/or a triphenylene group. The organic light-emitting device includes: a first electrode; a second electrode facing the first electrode; and an organic layer between the first electrode and the second electrode and including an organic layer, the organic layer including an emission layer and at least one of the heterocyclic compound.
