Abstract

The invention discloses a synthesis method and application of an ultra-short-wavelength photochromic diarylethene compound of an imidazole-thiophene aromatic heterocycle. The photochromic material can maintain good photochromic performance in a solution or a film, and is developed. The ring state has weak fluorescence in the range of 265-276 nm, while the closed-ring state has strong fluorescence in the range of 400-550 nm, which can be used for fluorescent light-controlled switches and anti-counterfeiting technology, and short-wavelength high-density holographic optical storage Materials, compared with symmetrical thiophene or benzothiophene perfluorocyclopentene materials, the cost of preparing materials is relatively low, and the application prospect is great.

Description

technical field

[0001] The invention relates to a synthesis method and application of an imidazole-thiophene aromatic heterocyclic ultrashort-wavelength photochromic diarylethene compound. Background technique

[0002] With the rapid development of information storage technology, people put forward higher and higher requirements for the capacity, data transmission rate and response time of optical information storage materials. The exploration of organic photochromic compounds as erasable and rewritable information materials is particularly attractive, because compared with inorganic materials, organic materials have high sensitivity, fast response, easy to form thin films, relatively low raw material prices, and can be passed through Chemical modification greatly adjusts the structure and properties of materials to meet storage requirements and other advantages, but there are also disadvantages such as poor photothermal stability and fatigue resistance. In recent years, th...
