英文摘要	The non-covalent interactions of chiral metal complexes with the achiral 5,10,15,20-tetrakis (4-sulonatophenyl) porphyrin (H(4)TTPS(2-)) have been investigated by UV-vis and circular dichroism (CD) spectra. The results show that under acidic environments, only the chiral complex cations ([CoBr(NH(3))(en)(2)](+), [Co(en)(3)](3+), [Ru(phen)(3)](2+)) could interact with H(4)TTPS(2-) to form chiral aggregates, accompanied with the metal-centered chirality information transferred to the formed J-aggregates. However, the chiral complex anion ([Co(edta)](-)) does not cause the self-assembly process. The competitive binding interactions between an achiral water-soluble cationic surfactant (N-hexadecyltrimethyl ammonium chloride, CTAC) and a cationic polyelectrolyte (polyallylamine, PAA) with the chiral metal complex H(4)TTPS(2-) J-aggregates, respectively, were also investigated. It was found that chiral-symmetry-breaking phenomena occur in the cationic surfactant induced event. In the case of a cationic polyelectrolyte, it could change the conformational flexibility of the H(4)TTPS(2-) aggregates. These results may lead us to understand the possible mechanism of the supramolecular self-assembly process by the non-covalent interactions.; National Natural Science Foundation of China[20973136, 20877099, 20972183]; State Key Laboratory of Natural and Biomimetic Drugs[20080208]; Hunan High Education Research Fund[06C068]; GUCAS (A B); Ministry of Science and Technology of China[2008AA100801]; Guangdong Province[2010B090300031]; CAS[2010B090300031]
