We have found that 5,11,17,23,29,35,41,47-octadodeca-noylcalix[8]arene-49,50,51,52,53,54,55,56-octol (2(8)C12) serves as a novel gelator of organic fluids. The properties and the formation mechanism of the gels were investigated in detail by using spectroscopic, optical microscopic, and thermographic methods.
