The interfacial behaviors of the non-typical amphiphilic compound p-methylphenylazo- calix[4]arene 1 and p-chlorophenylazocalix[4]arene 2 at the air/water interface and photo- chromism in the Langmuir-Blodgett films were studied by surface pressure-area isotherm and UV-Vis spectra. The results indicate that they can form stable monolayers at the air / water interface although they have no hydrophobic alkyl chains, and their LB film underwent reversible trans-cis photoisomerization on UV and daylight illumination.
