Interfacial assembly and supramolecular chirality of a series of Cu(Ⅱ)-coordinated Schiff bases complexes
Four achiral Cu(Ⅱ)-coordinated Schiff bases complexes containing aromatic structures were synthesized and their supramolecular assemblies at the air/water interface were investigated.All compounds could be spread on water surface although they have no alkyl chains.The Schiff base complex molecules with naphthyl groups formed J-aggregate in the LB films transferred from water surface.In AFM,a multilayer film or three-dimensional structures was observed.It is interesting to note that the LB films of achiral Cu-NA transferred from water surface showed chirality.The supramolecular chirality in these LB films was suggested to be due to a cooperative stereoregular stacking of the functional groups in a helical sense.This research work provides a helpful clue for regulating the nanostructures and supramolecular chiral assembly in organized films.
