Based on DFT calculations, we designed a series of 5‐phenylazopyrimidines with strong push–pull character in silico and observed very low energy barriers for the thermal ( Z )‐to‐( E ...
Photochromism does not have a rigorous definition, but is usually used to describe compounds that undergo a reversible photochemical reaction where an absorption band in the visible part of the electromagnetic spectrum changes dramatically in strength or wavelength. In many cases, an absorbance band is present in only one form. The degree of change required for a photochemical r… WebThe photochromism of 1-alkyl-2-(arylazo)imidazoles trapped in water pool by AOT -heptane reverse micelle . × Close Log In.
