Identification of oligo(p-phenylene vinylene)-naphthalene diimide heterocomplexes by scanning tunneling microscopy and spectroscopy at the liquid-solid interface.

Co-assembly of a melamine derivative covalently equipped with two oligo(p-phenylene vinylene) chromophores and a naphthalene diimide dye results in the formation of heterocomplexes at the liquid-solid interface which was shown using bias dependent imaging and scanning tunneling spectroscopy, despite the disordered nature of the assemblies.
