In this organogel structure, the p–p stacking interactions among the HPB moieties, the hydrogen-bonding interactions between the urea moieties, and the van der Waals forces between the long alkyl chains cooperatively stabilized the aggregate structure; these are well-known interactions in gel systems.2a,5 Specifically to clarify the effect of the hydroxyl group in the HPB unit on gelation, we also designed and synthesized reference compound 2, which does not contain an adjacent hydroxyl group and thereby cannot induce its planar keto tautomer upon excitation.
