Abstract

Addition of a small amount of coumarin during crystallization produces new polymorphic modifications in 4-styrylcoumarin and 4-(3-fluorostyryl)coumarin, which are photolabile. Interestingly, upon irradiation polymorphic modification of 4-(3-fluorostyryl)coumarin produces a mirror-symmetric photodimer in contrast to the centrosymmetric photodimer obtained without addition of coumarin during crystallization.
