Abstract

Self-aggregation of water-soluble pyridinium-substituted porphyrins with functionalized calixarenes leads to well-defined pH-tunable stoichiometries. Two assemblies with different porphyrin:calixarene ratios that crystallized at pH 2 and 6 have been structurally characterized. The Job plots of Soret band broadenings indicate that these structures are also preserved in solution.
