Abstract

NEW MATERIAL:A compound expressed by formula I (n is 4-8; m is 6-22). USE:A synthetic intermediate of amphipatic compound for functional built-up film. PREPARATION:A compound expressed by formula II is reacted with an acyl halide expressed by the formula CH3(CH2)m.COX (X is halogen) in the presence of a base (e.g. sodium hydride) in a solvent such as THF at ambient temperature to 100 deg.C to give the compound expressed by formula I. The compound expressed by formula I is reacted in the presence of anhydrous aluminum chloride in an organic solvent (e.g. nitrobenzene) to afford the calix arene derivative expressed by formula III. The compound expressed by formula III is a new substance, has high hydrophobic property, since the compound has long-chain acyl group and useful as an amphipatic compound and e.g. used as a functional built-up film by Langmuir Blodgett method.
