摘要：

(Chemical Equation Presented) Long and winding gel: Mixtures of (M)-and (P)-ethynylhelicene oligomers (see structure) differing in the numbers of helicene units formed organogels in toluene, which exhibited better thermoreversibility in the sol-gel process than those formed from enantiomers. Various twocomponent gels were obtained by changing the combination of the component pseudoenantiomeric oligomers, provided that they were larger than a trimer. © 2010 Wiley-VCH Verlag GmbH & Co.
