    • Abstract


      Copper sulphide clusters were prepared in Langmuir-Blodgett films of copper complexes of amphiphilic Schiff bases-3,4-dimethoxy-N-benzylidene hexadeylamine (I) and 3,4-dimethoxy-N-benzylidene-4’-(hexadecylamino) benzylamine (II) The clusters obtained were analysed using UV-Vis spectroscopy and optical microscopy. Brewster angle microscopic studies on monolayers ofI andII at air/water interface showed formation of needle-like domains which seem to cluster faster inI than inII. Atomic force microscopy (AFM) studies also showed fairly uniform sized clusters inII whereas in the case ofI they seem to show varying sizes. From the results it is concluded that π-elongation in the polar head groups leads to controlled cluster sizes in compoundII as compared to those in compoundI.
