Expertise:  inorganic/organic synthesis, spectroscopy, photochemistry

 

Alessio Orbelli Biroli was born on March 14, 1976. He obtained the degree in Chemistry at the University of Pavia on April 2, 2001 discussing a thesis entitled Self organized fluorescent systems for neutral species recognition in solution”.

In February 2005 he obtained the Ph. Doctoral degree in Chemical Science at the University of Pavia, Ph. D. thesis title Metal driven self-aggregation processes”.

May 2001-September 2001: Research cooperation at the University of Pavia.

November 2004-August 2005: Postdoctoral fellowship at the University of Pavia.

September 2005-August 2008: Research collaboration as “young researcher” on the project “Nano-organized or π-delocalised macro chromophores for nonlinear optics” (FIRB 2003) at the University of Milan.

September 2008-August 2009: Postdoctoral fellowship at the University of Milan to perform research on the project entitled “Symmetrically and asymmetrically substituted porphyrins for applications in solar cells and optical limiting” (PRISMA 2007).

September 2009-15th December 2009: Postdoctoral fellowship at the University of Milan to perform research on the project entitled “Design and use of new organometallic or coordination materials for third generation organic solar cells: Porphyrins and metalloporphyrins for application in solar cells” (CARIPLO 2008).

Since 16th December 2009 he has a permanent position as Research Scientist at the Institute of Molecular Science and Technology of the National Research Council (CNR-ISTM) of Milan.

He has been involved in several National projects funded by the Italian Ministry of University and Scientific Research (MIUR, FIRB 2003, PRISMA 2007), by CARIPLO Foundation (CARIPLO 2008) or by the European Community (FP7-NMP-2009 project 246124 ‘‘SANS’’); he is currently involved in a project funded by MIUR (PRIN 2010-2011 project 20104XET32 “DSSCX”).

He is co-author of 15 publications in international journals with high impact factor and several communications to national and international conferences.

His research activities can be divided into four main topics:

Supramolecular coordination chemistry: study of assembling and disassembling processes of ligands, containing a fluorescent fragment, promoted by metal ions in solution.

Nonlinear optics: nano-organization of NLO active organic chromophores on inorganic scaffold such as cyclotetrasiloxanes; theoretical and experimental study of dependence on the metal of the second order NLO responses of push-pull porphyrinic complexes substituted in meso position.

Photoluminescent materials: synthesis and study of models of the silica surface with photoluminescent chromophores, in particular terthiophene; design, synthesis and characterization of Er3+ complexes with fluorinated ligands for applications in telecommunications.

Photovoltaics: synthesis of push-pull porphyrinic photosensitizers, substituted in meso or in β-pyrrolic position, for DSSCs.
