| 英文摘要 | Supramolecular chirality and molecular self-assembly are important and interesting phenomena in living and non-living systems. in this work, supramolecular chirality of achiral pseudoisocyanine (pic) j-aggregates was successfully induced by d-, l-phenylalanine (phe) and other amino acids in nacl solution. the chiral j-aggregates showed a characteristic, induced circular dichroism (icd) in the visible region of j-band chromophore which depends on the absolute configuration, concentration and side groups of alpha-amino acids, as well as temperature. the atomic force microscopy images indicated that the j-aggregates exist in large bundles of entangled nanofibers, and the observed icd might result from the macroscopic helical arrangement of the assemblies. |
