Characterization ofN-hexadecyl-5-iminomethyl-8-hydroxyquinoline and oriented crystallization of CuSO4·5H2O under its monolayer

Abstract

A new amphiphilic ligand,N-hexadecyl-5-iminomethyl-8-hydroxyquinoline (HIHQ), has been synthesized in a convenient method and the characteristics of its monolayer on pure water and on a subphase containing copper ions investigated. LB films of HIHQ were studied by small angle X-ray scattering, UV–VIS and XPS spectra. An oriented crystallization was examined at the monolayer/water interface. A good selection of the (110) crystal face of CuSO₄ ·5H₂O occurred at the solid state of the monolayer due to the perfect match between this crystal face and the definite lattice structure of the monolayer.
