The organic photoelectric material provided by the invention not only has the characteristics of good thermal stability, high luminous efficiency, and easiness in processing and molding, but also has sufficient antibacterial and moisture resistant properties, and can be normally used in a humid environment, thereby greatly satisfying market demands.

Description

technical field [0001] The invention belongs to the technical field of photoelectric materials, and in particular relates to an organic photoelectric material and a preparation method thereof. Background technique [0002] Organic photoelectric materials are a class of photoelectrically active organic materials, usually organic molecules rich in carbon atoms and with large π-conjugated systems, including small molecules and polymers. Organic photoelectric materials have broad application prospects in the fields of organic light-emitting diodes, chip tubes, solar cells, and memories, and thus become one of the most popular research topics in the scientific and industrial circles. However, due to the short life of the device and low efficiency, the industrialization process is far below people's expectations. In addition, there are still many problems unresolved in the process of industrialization. Among them, rare earth complexes have superior optical, electrical, magnetic a...
