CHIRAL COMPLEXES OF ACHIRAL PORPHYRINS AND DIBLOCK COPOLYMERS
The chirality of molecules and supramolecular systems has attracted extensive interest of researchers because of its essential role in life and material sciences.12 Supramolecular chirality is usually achieved by noncovalent interaction. 5,10,15,20-tetrakis-(4-sulfonatophenyl)-porphyrin (TPPS) possessing zwitterionic character has been widely used in chiral supramolecular systems. Poly (ethylene glycol)-block-poly(4-vinylpyridine) (PEG-6P4VP) is able to form micelles in the presence of TPPS in acid aqueous solutions based on the electrostatic interaction between the protonated pyridines and negative charged sulfonate residues. TPPS can form highly ordered molecular J-and Haggregates at certain pH values in the micellar core.
