摘要：
An amphiphilic pyrene derivative (PyDNH3) bearing positively charged ammonium cations has been synthesized and characterized. Self-assembly of PyDNH3 in the presence of chiral tryptophan derivatives was investigated in ethanol/water by optical and chiroptical spectra, indicating the formation of helical aggregates. Scanning electron microscope (SEM) images showed the formation of ring-shape structures.
