Study of the aggregation of 1‐alkanoylperylenes in 1,4‐dioxane‐H₂O binary solvents—Derivation of a new empirical equation relating CAgC to both chain‐length and solvent aggregating power

Abstract

Aggregation behaviors of 1‐alkanoylperylenes (Pe‐n, n = 4, 8, 12) driven by hydrophobic‐lipophilic interaction (HLI) have been investigated in dioxane (DX)‐H2O binary aquiorgano solvents by means of fluorescence spectroscopy. A novel empirical equation, which rationalizes CAgC (critical aggregate concentration) dependence of the aggregates both on the chain‐length of the substituent alkyl group and on the solvent aggregating power (SAgP) for Pe‐n, has been derived.
