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

An intelligent light-emitting switch material with self-encryption function, a preparation method and an application thereof belong to the application field of intelligent light-emitting switch materials. The material is a divalent platinum compound formed with 4,4'-bis(trimethylsilylethynyl)-2,2'-bipyridine as the main ligand and 3-bromophenylacetylene as the auxiliary ligand. After the material combines n-hexane molecules and acetone molecules, it obtains two metastable states that cannot be distinguished by the naked eye under sunlight or ultraviolet light. Its color is yellow and its light is orange-red. After the two samples were heated at 120 °C, the color and luminescence of the metastable state combined with acetone molecules turned black, while the color and luminescence of the metastable state combined with n-hexane molecules did not change, thus showing the complex Self-encryption function. The introduction of this material makes the information encryption-decryption technology have the advantages of higher sensitivity, higher security, higher stability, lower cost, strong plasticity, easier operation, and recyclability.

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...
