摘要：

A homologous series of double-chain non-ionic surfactants with the general formula (C(n))2 GE(m)M, where C(n) denotes an alkyl chain, G a triglyceryl, and E(m)M an oligo-oxyethylene mono-methyl ether are synthesized with n = 6-8 and m = 6, 8, 10. The branched hydrophobic part of the surfactants introduces a large cross-section of the lipophilic surfactant moiety that is directly reflected in the shape of the micelles and the LC phase behavior in aqueous solution. The phase behavior of these V-amphiphiles is investigated with polarizing microscopy and x-ray diffraction and reveals that the branched lipophilic part strongly stabilizes the lamellar mesophase. This is in agreement with established packing models.
