Organic gelator : Diacetyl‐ and dinaphthyl‐terminated hydrazide‐based oligomers displayed gelation ability in apolar solvents due to hydrogen bonding and/or π–π stacking interactions, which promoted aggregation along one dimension. Their gels were solvent polarity sensitive. Because of complementary hydrogen‐bonding sites, when the ratio of the two gelators was 1:1 in apolar solvents, a multipoint directed supramolecular substitution reaction led to gel–sol transition (shown here).
