Embodiment 1

[0039] Example 1: Manganese complex PON(Me) 2 -MnBr 2 preparation

[0040] The specific synthetic route is as follows:

[0041]

[0042] (1) Triphenylphosphine oxide PON (Me) 2 The preparation method is as follows:

[0043] In a dry tetrahydrofuran solvent (20 mL) system at -78±5°C under the protection of nitrogen atmosphere, n-butyllithium (1.6M in n-hexane solvent, that is, the concentration of n-butyllithium in n-hexane solution is 1.6mol / L; 4.5mL, 7.2mmol) was added dropwise to the mixed system composed of N,N-dimethyl-2-bromoaniline (0.6mL, 4.8mmol) and tetrahydrofuran, when n-butyllithium was completely added, continuous Stir for 1.5h. After that, at -78±5°C, under nitrogen protection, diphenylphosphine chloride compound (1.3 mL, 7.2 mmol) was added dropwise, and then the ice bath was removed, followed by reaction at room temperature for 12 hours. After the reaction was completed, water (5 mL) was injected into the reaction system to completely quench n-butylli...

Abstract

The present invention discloses a novel neutral monodentate chelated manganese complex. By introducing different electron-donating and withdrawing substituents, such as N(Me), on triphenylphosphine oxygen ligands 2 , OMe, CF 3 , OCF 3 , Cl, F, CN, Br, can easily adjust the emission energy level and luminescence lifetime of manganese complexes, and then change the luminescence properties of materials; secondly, the use of neutral manganese complexes can realize the storage and protection of information.

Description

technical field [0001] The invention belongs to the technical field of photoluminescent materials, in particular to a neutral monodentate chelated manganese complex with different electron-donating and electron-withdrawing substituents, which can be used for information storage and protection. Background technique [0002] For centuries, paper has been the most important medium for humans to record information and spread civilization. With the rapid development of the information industry, more and more information is disseminated and obtained by people through the Internet, but people's reading habits of obtaining information from paper materials have not been fundamentally changed. It can be said that for a long time in the future, paper will still play a vital role in the dissemination and storage of information. [0003] However, for a long time, people have not been able to ensure that paper documents will not be accessed or taken away intentionally or unintentionally,...
