Research interests

My research interests are focused on the design and understanding of multi-properties molecular materials mainly based on redox-active tetrathiafulvalene (TTF) ligands and lanthanide ions.

  • Topic 1: Sensitization of lanthanide luminescence by antenna effect using TTF ligand as push-pull organic chromophore.
  • Topic 2: Use of magnetic anisotropy of lanthanide ion for the design of Single-Molecule Magnets (SMM)/Single-Chain Magnets (SCM) including magneto-structural correlation with optical properties.
  • Topic 3: Elaboration of 3d coordination complexes for the observation of thermal and photo-induced spin transition and 3d4f heterobimetallic complexes for combination with SMM behavior.
  • Topic 4: Use of chiral ligands with high optical activity value for the design of chiral SMM.
  • Topic 5: Electro-crystallization of the multi-properties molecular materials for electronic conductivity studies and switching of the physical properties.
  • 71 international articles (H factor=26)
  • 3 Book chapters
  • 10 Invited conferences
  • 7 Invited seminars in international Laboratories
  • 15 Oral Communications
  • 28 Posters presentations
  • 3 Doctoral workshops
  • 4 Organizing committee of scientific conferences
