Embodiment Construction

[0018] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0019] Step 1: Preparation of Pt(II) smart light-emitting switch complex with self-encryption function.

[0020] [4,4'-bis(trimethylsilylethynyl)-2,2'-bipyridyl]platinum dichloride intermediate and 2.5 equivalents of 3-bromophenylacetylene, 0.001-0.10 equivalents of cuprous iodide, sequentially Add it into anhydrous diisopropylamine and dichloromethane (volume ratio 1:10) solution, and stir at room temperature under nitrogen protection for 24 hours. After the reaction was completed, the solvent was distilled off under reduced pressure, and then separated and purified by column chromatography to obtain the product with a yield of 83%. Elemental analysis results: press C 36 h 32 Br 2 N 2 PtSi 2 Calculated (%) C 47.85, H 3.57, N 3.10; found (%) C 47.88, H 3.61, N 3.05. 1 H NMR (500MHz, DMSO, ppm): 9.447...

Abstract

The invention discloses an intelligent light-emitting switch material with a self-encryption function as well as a preparation method and application thereof, and belongs to the field of application of intelligent light-emitting switch materials. The material is a divalent platinum compound formed by taking 4, 4'-bis (trimethylsilylacetylene) 2, 2'-dipyridyl as a main ligand and 3-bromophenylacetylene as an auxiliary ligand. After the material is combined with normal hexane molecules and acetone molecules, two metastable states which cannot be distinguished by naked eyes under sunlight or ultraviolet light are obtained; the color of the metastable states is yellow; and light emitted by the metastable states is orange red. After two samples are heated at the temperature of 120 DEG C, the color and light emission of the metastable state combining the acetone molecules become black, and the color and light emission of the metastable state combining the normal hexane molecules are not changed, so that the self-encryption function of the complex is shown. Due to the introduction of the material, the information encryption and decryption technology has the advantages of higher sensitivity, higher security, higher stability, lower cost, high plasticity, easier operation, recyclability and the like.

Description

technical field [0001] The invention belongs to the technical field of synthesis and application of intelligent light-emitting switch materials, and in particular relates to the preparation of an intelligent light-emitting switch material with self-encryption function and its application in the field of information security storage. Background technique [0002] Modern society is called "information society". Information technology has penetrated into all departments in the political, economic and industrial fields, and the proportion of information industry in the national economy is increasing. With the development of the Internet, Internet of Things, mobile Internet, big data and other fields, social informatization has reached an unprecedented height, which has greatly stimulated my country's economic development. The higher the degree of social informatization, the more information data is generated, the more prominent the problem of information security. While enjoyin...
