preparation example Construction

[0024] The method for the compound shown in the preparation formula I provided by the present invention specifically comprises the following steps:

[0025] (1) In the presence (protection) of an inert gas (a gas that does not participate in the reaction, such as argon, etc.) and under light-shielding conditions, the compound shown in Formula IV and the solvent are placed in a dry round-bottomed flask, at (-15 ° C) ~-10°C), add n-BuLi cyclohexane solution to the round bottom flask, after the addition is complete, stir at room temperature for at least 45 minutes, then add trimethyl borate, and continue stirring for at least 4 hours to obtain the formula III Compound shown (no need for separation and purification, can be directly used in the next step);

[0026] (2) In the presence (protection) of an inert gas (a gas that does not participate in the reaction, such as argon, etc.), add an aqueous solution of potassium carbonate to the tetrahydrofuran (THF) solution of the corresp...

Abstract

The invention relates to a triphyene derivative containing diarylethene and an application thereof. The triphyene derivative is obtained by the way that triphyene derivative halogeneated triphyene and bisthienylethenes containing trimethyl borate are in coupled reaction. The designed and compounded triphyene derivative has the characteristics of being good in heat stability, high in quantum efficiency, short in light response time and the like. In addition, a unique solvation color development phenomenon is shown in triphyene derivative alkane chloride. Consequently, the triphyene derivative containing the diarylethene not only can be used for full color display and information storage but also can be used for trace detection of the alkane chloride.

Description

technical field [0001] The invention relates to a triptycene derivative and its application, in particular to a triptycene derivative containing diarylene and its application. Background technique [0002] In today's society, science and technology continue to develop rapidly. The application of various advanced information technologies has been closely related to people's work, study and life. We are in an era of information explosion. However, the existing hardware conditions make it impossible for various cutting-edge technologies to be put into application in time, and it is increasingly unable to meet people's growing demand for information storage and transmission. Therefore, information storage materials with high density, fast response, and reusability have become the research focus of many scientific researchers. Photochromic materials have great application potential in information storage and other fields, and have attracted much attention. Among various photoc...
