Crown-substituted naphthalocyanines: synthesis and supramolecular control over aggregation and photophysical properties†
Abstract
Tetra-15-crown-5-naphthalocyanines as first representatives of crown-substituted π-extended phthalocyanines were synthesized and characterized. The possibility to control their aggregation and photophysical properties by reversible formation of supramolecular assemblies in the presence of KOAc was demonstrated.
