Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent， Formula: C11H13N, Which mentioned a new discovery about 1640-39-7
A number of photochromic indolinospirochromenes that contain an octadecyl substituent in the 1 position were synthesized.The introduction of an octadecyl group in place of a methyl group increases the stability of the merocyanine form in solution but does not change its spectral characteristics.On the other hand, the introduction of phenyl groups in place of methyl groups in the 3 position does not change the stability of merocyanine but gives rise to a bathochromic shift of the long-wave absorption band.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1640-39-7, help many people in the next few years.Safety of 2,3,3-Trimethylindolenine
