摘要

The synthesis of bolaamphiphiles with two amino acid heads having the general structure AA-X-AA, where AA denotes an amino acid (D- or L-alanine or L-histidine) and X an alkyl chain of varying length, is described. Micellization was observed for the bolaamphiphile with a twenty-carbon atom alkyl chain. For compounds with shorter chain lengths, light scattering and electron microscopy suggest the formation of vesicles or fibrous aggregates. These bolaamphiphiles can also form gels at higher concentrations in water or ethanol. Fibrous structures were observed in these gels by electron microscopy. [References: 44]
