Description

technical field [0001] The present invention relates to an indoline spiropyran derivative with photochromic properties, ion detection function and thermal and photochemical stability at the same time. Background technique [0002] The discovery of photochromic phenomenon has a history of more than 100 years. The earliest report was Meer, who in 1876 discovered that the potassium salt of dinitromethane had a reversible change in color under the action of light. In 1899, Markward discovered that l,4-dihydro-2,3,4,4-tetrachloronaphthalene-1-one also had a reversible color change under the action of light, and called this phenomenon photochromic interconversion. . [0003] As a photochromic compound, indoline spiropyran is the most extensive and in-depth class of research. In 1952, Fisher and Hirsthberg discovered its photochromic phenomenon. In 1956, Hirstberg proposed that it can be used as a photochemical memory and a The possibility of variable-density optical shutters ha...

AI Technical Summary

Problems solved by technology

At present, the vast majority of indoline spiropyran compounds have poor thermal and photochemical stability as optical storage media, and the discoloration recovery time is short, and the recorded information cannot be stored for a long time.

Indoline spiropyran derivatives with photochromic properties, ion detection function and thermal and photochemical stability have not been reported yet
