Nanoscale morphology of bis(1-anthraquinoxy)glycols

The nanoscale morphologies on a series of new anthraquinone substitutes have been carried out. Among the substitutes, only bis[2-(1-anthraquinonoxy)- ethyl]ether in a mixture of dichloromethane/acetone (1/1) slowly forms uniform nanowires with 80-120 nm diameters. The same compound in a mixture of dichloromethane/tetrahydrofuran (1/1) slowly produces uniform nanobelts with 400-600 nm widths. Thus, both the spacer lengths and the solvent effects of the compounds are important factors for the formation of nanoscale morphologies. The nano patterns seem to be formed by the π-π interactions between the anthraquinone moieties.
