Two kinds of Schiff bases, 85 samples of N-(benzylidene)-anilines (ZBAY) and 83 samples of N-(phenyl-ethylene)-anilines (ZAPEY), were used as model compounds, in which the ZBAY contains 13 compounds with 2-OH and the ZAPEY contains 35 compounds with 2-OH
Study of Photochromism in the Anils of o-Hydroxyacetophenone, o-Hydroxybenzophenone and 2'-Hydroxydeoxybenzoin

The photochromic activity of anils (VI) of o-hydroxyacetophenone, o-hydroxybenzophenone and 2'-hydroxydeoxybenzoin has been investigated in methylcyclohexane-pet. ether (40 - 60 deg C) at -180 deg C and in liquid paraffin at -75 deg C.No photocoloured species has been observed in any of these anils after irradiation with 365 nm wavelength in rigid glassy solutions.This is most likely due to the increased height of potential energy barrier which in turn is caused by the increased basicity of the imine nitrogen because of positive inductive effect of methyl, benzyl and phenyl groups substituted in place of aldehydic proton.
