Document Type and Number:
WIPO Patent Application WO/2020/082605
Kind Code:
A1
Abstract:
The present invention relates to a pyrazolyl azophenol compound and the synthesis and derivation thereof. Specifically, the compound is 4-((1-methyl-1H-pyrazol-4-yl)diazenyl) phenol, and the structure thereof is as follows: formula I. The method for synthesizing 4-((1-methyl-1H-pyrazol-4-yl)diazenyl) phenol is simple, and a plurality of azobenzene light-responsive functional molecules having long half-life Z isomers may be derived by means of phenolic hydroxyl groups. Compared to the prior art, the raw materials of the pyrazolyl azophenol compound provided by the present invention are easy to obtain, the process of synthesis is simple, yield is high, and mass production is easy. Etherification and esterification reactions of the compound are both classic organic reactions, and have the advantages of mild condition and high yield. In summary, the present invention provides a convenient way for the development and utilization of azobenzene light-responsive functional molecules having long half-life Z isomers.
