Embodiment Construction

[0026] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0027] Step 1: Preparation of [5,5'-bis(trimethylsilylethynyl)-2,2'-bipyridine]platinum dichloride. Take an equivalent amount of 5,5'-bis(trimethylsilylethynyl)-2,2'-bipyridine and dimethyl sulfoxide platinum chloride and stir in anhydrous acetonitrile for 8 hours under nitrogen protection. The product was separated by silica gel column, and the yield was 70-75%. Elemental analysis results: press C 20 h 24 Cl 2 N 2 PtSi 2 Calculated (%) C39.09, H3.94, N4.56; found (%) C39.12, H3.93, N4.54. 1 HNMR (CDCl 3 ): 0.313(s,18H), 7.875(d, J(H,H)=4.8Hz,2H), 8.154(d,J(H,H)=4.8Hz,2H), 9.861(s,2H).

[0028]Step 2: Preparation of Pt(II) complex luminescent and color-changing material. Under nitrogen protection, take the product obtained in step 1, 2.5 equivalents of m-bromophenylacetylene, and 0.05 equivalents o...

Abstract

The invention belongs to the field of synchronization and application of light-emitting off-color materials, discloses a preparation method and application of a light-emitting off-color material with an information security storage function, and belongs to the field of application of visible light emitting off-color materials. The light-emitting off-color material is a complex prepared from platinum (II), 5,5'-di(trimethyl acetenyl)-2,2'-dipyridyl ligand and 3-bromo-phenylacetylene auxiliary ligand. According to different responses of color and light emission of the light-emitting off-color material to tetrahydrofuran steam, the material can be used in security storage of information. In addition, the material not only has advantages of high sensitivity, high security, high stability, visibility, low cost, good plasticity, easiness in operation, recyclable use and the like, but also has wide application prospects and relatively high commercial values in the field of information security materials.

Description

technical field [0001] The invention belongs to the field of synthesis and application of luminescent and color-changing materials, and in particular relates to a preparation method and application of a luminescent and color-changing material with information security storage function. Background technique [0002] In today's society, information security is of vital importance in people's daily life and production, especially in economic and military fields. Once information leakage occurs, the consequences will be disastrous. Therefore, it is particularly important to find safe and effective information storage methods. At present, information storage materials mainly involve substances that have special responses to signals such as light, electricity, and magnetism. Because the preparation of traditional information storage materials is quite complicated, the cost is high, the operation procedures are complicated, the technical content is high, and specific complex instr...
