Changes of Aqueous Self-assemblies of Zinc Chlorophyll Derivatives Possessing a Hydrophilic Chain by Treatment with Organic Solvents

摘要

Visible absorption and circular dichroism spectra of zinc chlorophyll derivatives possessing an oligo(oxyethylene) moiety at the 17-propionate in aqueous media were drastically changed by treatment with dichloromethane or chloroform, indicating that dimeric and monomeric species were converted into chloro-some-like large self-aggregates.
