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.

Scientific career:

  • 2006 BSc in Chemistry at the Benemerita Universidad Autonoma de Puebla (BUAP, Mexico).
  • 2006-2007 Project Scientist at York University (Canada) under the supervision of Clifford C. Leznoff.
  • 2012 Ph. D. in Synthetic Organic Chemistry at the University of East Anglia (UEA, UK) under the supervision of Michael J. Cook and Andrew N. Cammidge.
