Research interests:

Molecular self-assemblies, molecular design, π-conjugated macromolecules, functional surfaces, organic electronics, hybrid materials, STM, HOPG/graphene, liquid crystals.

Current research:

Design, synthesis and STM studies of supramolecular architectures on metal and graphene for plasmonic luminescence excitation.

Recent results:

  • Development and tuning of new optoelectronic, light-emitting devices from nanometric electroluminescent diodes based on organic molecular wires (nanowires).
  • Molecular engineering of surface-confined, supramolecular luminescent architectures.
  • Characterisation of molecular self assemblies on HOPG/graphene by STM at the solid-liquid interface.
