Abstract

The invention provides a preparation method of a binuclear rhodamine bispyrazole acetate organic laser material. The preparation method comprises the steps of preparing rhodamine bispyrazole acetate,preparing binuclear rhodamine bispyrazole acetate, and the like. The binuclear rhodamine bispyrazole acetate organic laser material provided by the invention is low in preparation cost, simple and controllable in synthesis, high in yield, good in dissolvability, and better in heat stability at the same time. The material shows excellent heat stability, film formation stability, low threshold valueproperty, low water-oxygen sensitivity and high illumination intensity when being applied to an organic laser device. With high luminous efficiency and migration rate, the material has a potential application value on electrical pump organic semiconductor lasers, organic electroluminescence and organic field effect transistors.

Description

technical field [0001] The invention belongs to the field of laser materials, in particular to a dual-core rhodamine bispyrazole acetate organic laser material. Background technique [0002] Traditional lasers have many problems, such as solid-state lasers, which face problems such as crystal growth difficulties, high technical requirements, and high prices; laser glass generally needs to be melted under high temperature conditions, for different matrix materials and different laser working bands It also needs to remove OH groups and gas protection, the process conditions are harsh, and the production cost is high. At present, more carbon dioxide gas lasers are used. Although the power is high, the devices are bulky and bulky, which brings a lot of inconvenience to occasions that require miniaturized lasers. In recent years, inorganic semiconductor lasers have been developed rapidly and widely used, but there are also problems of high production costs. In view of the limit...
