-

Paragraph 0037; 0040; 0043, (2021/11/03)

The invention provides a cyanine type modified compound with the structure of the formula (I), and also provides a preparation method of the cyanine type modified compound. The Vinamidinium-salt new synthetic route is developed, the process parameters are optimized, the yield of the intermediate is improved, the product quality is also good, and the effect of increasing the yield of the next step is crucial. In addition, since the cyanine-based modified compound contains more double bonds and strong electron-withdrawing groups, it can be used as an ultraviolet - blue light absorbent.
