title: Self-aggregation of zinc chlorophylls possessing perfluoroalkyl chains in fluorous solvents: Selective extraction of the self-aggregates with fluorous phase and accelerated formation of the ordered supramolecules in this phase.
abstract: Zinc 3(1)-hydroxy-13(1)-oxo-chlorins possessing various perfluorooctyl groups in the 17-propionate were prepared by modifying naturally occurring chlorophyll-a. The synthetic compound having four perfluorooctyl groups readily self-assembled to form large J-aggregates, which were dissolved in fluorous phases with more ordered supramolecular structures than in a hydrocarbon solvent.
