Abstract

The invention discloses a pyridine anthracene derivative platinum coordination compound as well as synthesis and an application thereof. The pyridine anthracene derivative platinum coordination compound takes a pyridine derivative platinum complex as the center, an anthracene group is added, and the triplet state of the whole molecule is reduced, so that near infrared emission is realized. Besides, the function of the MCLT (metal-to-ligand charge transfer) state and the dual function of MMLCT (metal-metal-to-ligand charge transfer) state are realized under the molecular arrangement effect of the anthracene group, and dual phosphorescence emission is realized. The pyridine anthracene derivative platinum coordination compound can be applied to temperature detection and used as an electroluminescent material and is a novel temperature detection, single-molecular white light and near infrared luminous material. Through improvement of key chemical structures and the preparation process of the pyridine anthracene derivative platinum coordination compound, the novel temperature detection, single-molecular white light and near infrared luminous material based on the pyridine anthracene derivative platinum coordination compound is obtained, and the preparation method is simple and feasible.

Description

technical field [0001] The invention belongs to the technical field of preparation and application of organic photoelectric materials, and more specifically relates to a platinum coordination compound of pyridine anthracene derivatives and its synthesis and application. The platinum coordination compound material of pyridine anthracene derivatives is especially suitable as a temperature Detection and organic light-emitting materials are used in the fields of temperature detection and light emission. Background technique [0002] Temperature is one of the most fundamental and important physical quantities in the fields of science, technology, industrial applications and in all aspects of daily life. Traditional liquid or glass thermometers and thermocouple thermometers need to be in contact with the measured object during the measurement process. Under extreme measurement conditions, this thermal contact measurement method will have considerable limitations. Generally speaki...
