| Abstract: | Mixed monolayers of Schiff-base complex Cu(SBC18)2 with an octadecyl hydrocarbon chain and Calix4]arene without a long alkyl chain at an air/water interface were studied in ultrapure water at different temperatures. Interface behavior and thermodynamic estimation of the mixed monolayer indicate that a strong intermolecular interaction exists between the mixed components (Cu(SBC18)2 and calix4]arene) and the two-dimensional miscibility decreases with the molar fraction of Cu(SBC18)2. It is noticeable that the calix4]arene monolayer can be transferred successfully onto solid substrates due to the introduction of Cu(SBC18)2. FTIR transmission and UV-Vis absorption spectra of mixed LB films provide further evidence of molecular interaction between the headgroups. |
