Luminescent lanthanide-based molecular
materials. Design, synthesis, characterization and
study of the photophysical properties of luminescent molecular materials,
either single molecules and extended networks such as MOFs, HOFs and COFs, based
on lanthanides, with particular focus on near-infrared emitters for application
in photonics, specifically for signal amplification in telecommunication
technology as well as visible emitters for anticounterfeiting and sensing.
Heterolanthanide molecular materials, either as discrete molecules and extended
frameworks are also developed. Interest is also directed towards the processing
of these compounds as hybrid materials (doped glasses, polymers) and thin films
for functional devices.
Luminescent lanthanide-based nanomaterials. This research line is oriented towards luminescent nanostructured
materials with the aim to achieve more efficient emission performances by
overcoming the limitations of molecular complexes (vibrational quenching) and
novel potential applications. In particular, current research interests are
focused on multilayered nanoarchitectures based on silica, fluorides and lead
halide/lead free perovskites combined with luminescent lanthanide ions. These
materials are deeply investigated through steady-state and time-resolved
techniques, including ultra-fast transient absorption experiments.
Mono- and multifunctional molecular
materials. Design, synthesis, characterization and
study of the optical (linear and non-linear properties), magnetic and
conducting properties of d and f metal complexes with suitable
organic ligands showing simultaneous or cooperative multifunctionalities. In
this framework, of particular interest in recent times, are square-planar Ni-triad
complexes as NLO-phores, also showing unusual optical properties with
anti-Kasha emissive behavior responsive to external stimuli (pH, presence of
metal ions).
Green chemistry. This
research line is addressed to the recovery, recycling and revalorization of
noble and precious metals (Au, Pd, Ag, Cu) as well as lanthanides (Nd, Dy, Sm)
from electronic waste with green chemistry approaches. Strategies for the
efficient leaching of these metals from scrap materials have been studied with
the use of opportunely functionalized ligands with the double role of chelating
and oxidizing agents. The products of these treatments can afterwards be
re-employed as valuable resources for applicative purposes (e.g. phosphors).
More recently, strategies for the direct refunctionalization of Nd and Dy from
end-of-life supermagnets as luminescent materials are developed in the
framework of the PRIN2022 project “GREEn SM”.
