Stilbene-cored dendrimers having benzophenone peripheries with alkyl chains formed 1 µm and 4 nm aggregates in methylcyclohexane (MCH) for trans-1 and trans-2, respectively. Even in the aggregates, trans-1 underwent efficient trans–cis photoisomerization from the excited triplet state produced via intramolecular two-step energy transfer.
