Interfacial Assembly and Coordination of a Series of Schiff Base Compounds with Aromatic Spacer

摘要

A series of Schiff bases derivatives with aromatic spacer have been designed and their interracial phase behaviors and coordination with Cu(Ⅱ) ions were investigated.It has been found that on the subphase containing Cu(Ⅱ) ions,all of the Schiffbases can coordinate with Cu(Ⅱ) in situ in the spreading films,especially for NSB-C 16 with the obvious conformational change of alkyl chains.The in situ Cu(Ⅱ)-coordinated films could be transferred onto solid substrates and subsequently characterized by various spectroscopic methods such as UV-vis and Fourier transform infrared spectra as well as the morphological characterization with atomic force microscopy measurement.Depending on the different groups,these amphiphiles showed different aggregation behaviors in the Langmuir-Blodgett films.
