Title: Interfacial binding of divalent cations to calixarene-based Langmuir monolayers

Abstract

The interactions of Langmuir monolayers produced through the self-assembly of an amphiphilic p-carboxycalix[4]arene with a series of divalent, fourth-period transition metals, at the air-water interface, were investigated. Changes in the interfacial behavior of 1 in response to the presence of CuCl 2, CoCl 2, MnCl 2, and NiCl 2 were studied by means of Langmuir compression isotherms and Brewster angle microscopy (BAM). The measurements revealed that the self-assembly properties of 1 are significantly affected by Cu 2+ ions. The interactions of 1-based monolayers with Co 2+ and Cu 2+ ions were further investigated by means of synchrotron radiation-based X-ray reflectivity (XRR), X-ray near-total-reflection fluorescence (XNTRF), and grazing incidence X-ray diffraction (GIXD). XNTRF and XRR analyses revealed that the monolayer of 1 binds more strongly to Cu 2+ than Co 2+ ions. In the presence of relatively high concentrations of Cu 2+ ions in the subphase (1.4 × 10 -3 M), XNTRF exhibited anomalous depth profile behavior and GIXD measurements showed considerably strong diffuse scattering. Furthermore, both measurements suggest the formation of Cu 2+ clusters contiguous to the monolayer of 1.
