US 12,624,014 B2 · Fluorescent material containing thiophene sulfone-olefin structural unit and preparation method thereof

Abstract

A fluorescent material containing a thiophene sulfone-olefin structural unit and a preparation method thereof are provided. In the preparation method, the thiophene sulfone compounds, olefins, oxidants and additives are dissolved in the tetrahydrofuran solvent, and are subjected to a reaction under the catalytic action of the palladium catalyst, and the alkenylated thiophene sulfone products with obvious fluorescence emission characteristics of liquid and solid can be obtained. The preparation method expands the range of substrates well, featuring good regional selectivity, high yield, mild reaction conditions and simple operation.
