By
means of conventional structure determination techniques form single
crystal X-ray diffraction, Simona Galli focused her research activities
on the structural aspects of polyazolato-based
coordination polymers possessing solid state, second order non linear
optical properties.
More recently, she has widened
her interests to include structure determination methods from X-ray
powder diffraction (XRPD) data. As a complementary technique, she also
makes use of in situ
variable-temperature XRPD, even in conditioned atmosphere, to characterise
sorption-desorption processes or phase transitions.
Her XRPD structural
characterizations principally focus on thermally stable coordination polymers
built up by combining transition metal ions and poly(azolate)
ligands and possessing functional properties
such as second order NLO, magnetism, molecular recognition, permanent
porosity. The latter functional property has represented and still
represents her main research interest, as witnessed by the numerous
publications on the subject in international scientific journals and by
the deposition of an internationally granted patent.
During the past year, she has
promoted the development of a research line devoted to coordination
polymers containing perfluorinated spacers,
with the aim of isolating low dielectric constant materials. The
structural characterization is here complemented by impedance measurements.
Scientific collaborations have been or are at
work with national and international research groups, at the University
of Milano, the University of Camerino, the University of Turin, and the University of Sassari, in
Italy; the University of Granada and the CSIS of Oviedo, in Spain; the University of North Texas, the Northwestern University of Chicago, the University of California,
Berkeley, in the USA.
