Some trigonal Schiff base amphiphiles with symmetric aromatic cores and different substituted headgroups were designed and their interfacial assemblies were investigated. When on the metal ions subphases, an in situ coordination can occur for all compounds. The coordinated films could be transferred onto solid substrates and subsequently characterized by morphological characterization with atomic force microscopy measurement. Depending on the trigonal molecular structures and different substituted headgroups, these amphiphiles showed distinct assembly behaviors in the organized molecular films.

A series of Schiff bases derivatives with aromatic spacer have been designed and their interfacial 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 Schiff bases can coordinate with Cu(II) in situ in the spreading films, especially for NSB-C16 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.

wo bolaform Schiff bases derivatives with aromatic spacer have been designed and their interfacial phase behaviors and coordination with Cu(II) ions were investigated. It has been found that on the subphase containing Cu(II) ions, both Schiff bases can coordinate with Cu(II) in situ in the spreading films. 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 headgroups, both amphiphiles showed different aggregation behaviors in the Langmuir-Blodgett films.

Insight Into

Great interest has been given to the Schiff base amphiphiles with special molecular structures because of their unique properties. In this article, we report some interesting properties of the interfacial films formed by a newly designed trigonal amphiphiles Schiff base containing hydrophobic core and aromatic periphery. This novel Schiff base amphiphile could be spread to form stable monolayers and coordinated with Cu(Ac)2 in situ in the monolayer. The coordination with Cu(II) ion has a great effect on the regulation of the properties of the Langmuir monolayers. A larger limiting molecular area was observed for the monolayers of the trigonal amphiphile on Cu(II) ions subphase. Both the monolayers on water and on the aqueous Cu(Ac)2 subphase were transferred onto solid substrates, and different morphologies were observed for films. The present work provided new insight into the design and interfacial assembly of novel Schiff base amphiphiles with special molecular structures and substituted groups.
