peripheral functional groups on the [4+4]-photocycloaddition between substitutedanthracene derivatives was examined. The reactivity of 2,3,6,7-tetraphenylanthracene (TPA) with 2-phenylanthracene (PA), 2,9,10-trimethylanthracene (TMA) and 9,10-dimethyl-2,3-diphenylanthracene (DMDPA) was investigated. In all cases, the photodimers were formed in high yield despite the steric bulk of the peripheral substituents
