Photochromic bi-thiophene six-sugar water-solubility symmetrical octafluorocyclopentene compound and preparation method and application

Abstract

The invention discloses a photochromic bi-thiophene six-sugar water-solubility symmetrical octafluorocyclopentene compound and a synthetic method and a purpose thereof. A photochromic material can maintain good photochromic performance in solutions or films, the superior performance of a high cyclizing quantum yield, good sensitivity and the like is achieved in a open-loop state (a colorless state) and a closed-loop state (a color generation state), the open-loop state has strong fluorescent light occurs in a 350-550 nm range, luminance of the fluorescent light is reduced along with increasing of ultraviolet light emission time, and the closed-loop state has no fluorescent light, so the compound can be used for fluorescence detection and fluorescence light-operated switches. Compared with symmetrical thiophene or benzo thiophene type octafluorocyclopentene materials, the compound is low in cost of prepared materials and wide in application prospect.

Description

technical field [0001] The invention relates to a photochromic thiophene-linked hexavalent sugar water-soluble symmetrical perfluorocyclopentene compound, a preparation method and an application. Background technique [0002] With the rapid development of information storage technology, higher and higher requirements are put forward for the capacity, data transmission rate and response time of optical information storage materials. Exploring organic photochromic compounds as erasable and rewritable information materials is particularly attractive, because compared with inorganic materials, organic materials have high sensitivity, are easy to form thin films, and can greatly adjust the structure and properties of materials to meet storage requirements. , The price of raw materials is relatively low, but there are also disadvantages such as poor light and heat stability and fatigue resistance. In recent years, photochromic organic compounds with excellent properties have beco...

Problems solved by technology

[0003] At present, in perfluorocyclopentene diarylethene compounds, the aromatic rings connected to both ends of the ethylene double bond are mainly two five-membered aromatic heterocycles, thiophene and benzothiophene, and there are also a small number of reports using furan, indole , pyrazole and indene as the main structure, but they are fat-soluble diarylethene compounds, which limits the application of such compounds in some fields, such as in biology
