Abstract
A new monoclinic polymorph, form II, of 3,4-dimethoxycinnamic acid has been isolated and shows a different photochemical and photomechanical property from the previously reported triclinic form I. The solid-state 2 + 2 photodimerization of these polymorphs is rationalized on the basis of minimum and maximum molecular movement during the reaction – the so-called Kaupp and Schmidt models for these reactions.
