Abstract

UV-visible spectral observations indicate that the J-aggregation of protonated meso-tetra(4-sulfonatophenyl)porphyrin ([H₂TSPP] ²⁺) under acidic conditions is completely inhibited by the π-π counteraction between 1-butyl-pyridinium tetrafluoroborate ([bpy]BF₄) and [H₂TSPP]²⁺. The studies also suggest that the intermolecular π-π force is of relative importance for the J-aggregates of [H₂TSPP]²⁺ and the intermolecular electrostatic force for the H-aggregates.
