Negative photochromism of new spirooxazine derivatives in acidified solution
Three new spirooxazines derivatives have been investigated in neutral and acidic ethanol solution. Besides, the classical photochromic and thermochromic properties of spirooxazines compounds, a strong reversible visible-light photobleaching of the protonated open form has been found. A global mechanism is proposed.
