| introduction | 2-(2-hydroxyphenyl) benzothiazole and other fluorescent substances as OLED luminescent materials have been deeply studied by chemists all over the world. 2-(2-hydroxyphenyl) benzothiazole (2-(2-hydroxyphenyl) benzothiazole) produces a strong fluorescence phenomenon, mainly the hydroxyl group and the lone pair of electrons on N form hydrogen bonds, so that the entire molecule forms a stable planar structure. The five-membered heterocyclic ring and the six-membered hybridization formed by hydrogen bonds form a chromophoric group that is easy to flow of electrons, and is irradiated by ultraviolet light, absorb energy, resulting in electronic transition, resulting in a strong fluorescence effect. |
| Uses | 2-(2-hydroxyphenyl) benzothiazole and other fluorescent substances as OLED luminescent materials have been deeply studied by chemists all over the world. 2-(2-hydroxyphenyl) benzothiazole is mainly used as a luminescent material. |
| Preparation | Robert G Charles, etc. uses salicylamide and o-aminophenyl mercaptan as starting materials, and reacts at 220 ℃ in an oil bath for 4~5 h, and then undergoes vacuum distillation, recrystallization purification, drying and other steps to obtain the final product 2-(2-hydroxyphenyl) benzothiazole, the yield 72% [1], the reaction is shown in Figure 1. The synthetic route does not need to add solvents, and the operation is fast, but the raw material of the reaction is more toxic, and the reaction temperature is higher, so protective measures must be taken during the operation.
