Chemical Properties
white solid powder
A new donor moiety, 7,7,13,13-tetramethyl-7,13-dihydro-5H-indeno[1,2-b]acridine (IAc), was developed to control the highest occupied molecular orbital (HOMO) dispersion of thermally activated delayed fluorescent (TADF) emitters. The IAc unit expanded the HOMO dispersion of the emitters and increased the quantum efficiency of the TADF devices up to 20.9 %.
The invention belongs to the technical field of organic materials, and provides a nitrogen-containing compound, and an organic electroluminescent device and an electronic device using the same. The nitrogen-containing compound has a structure as shown in a formula I, wherein X1, X2 and X3 are respectively and independently selected from N or CH, and at least one of X1, X2 and X3 is N. When the nitrogen-containing compound is used in the organic electroluminescent device, the performance of the device can be improved.
The present application provides a compound of formula (I), which may be used in an electron transport material.
