Enhancement of SOD activity in boehmite supported nanoreceptors
2018
The binuclear Cu2+ complex of a pyridinophane polyamine ligand ranking amongst the fastest SOD mimetics so far reported displays a remarkable SOD activity enhancement when grafted to the surface of boehmite (γ-AlO(OH)) nanoparticles (BNPs).
Grafted squaramide monoamine nanoparticles as simple systems for sulfate recognition in pure water.
2012
New simple systems formed by a chain containing a squaramide function and a quaternised amine group attached to boehmite or silica-coated boehmite nanoparticles are able to discriminate anions in pure water.
One-pot preparation of surface modified boehmite nanoparticles with rare-earth cyclen complexes.
2007
We report on the one-pot synthetic procedure of cyclen derivatives bearing three acetate groups attached on boehmite nanoparticles, the complexing capabilities of these inorganic–organic hybrid materials with rare earth cations, and the behaviour as contrast agents or fluorescence probes.

A new chromo-fluorogenic probe based on BODIPY for NO2 detection in air
2014
[EN] A novel colorimetric probe for the selective and sensitive detection of NO2 in solution and in air based on a BODIPY core containing an oxime group has been prepared.
First bodipy–DOTA derivatives as probes for bimodal imaging
2010
The synthesis and the photophysical studies of the first bodipy-DOTA and its In(III), Ga(III) and Cu(II) complexes are reported. The introduction of an isothiocyanate handle generates a new bimodal imaging agent capable of both optical and nuclear imaging.
Chromo-fluorogenic BODIPY-complexes for selective detection of V-type nerve agent surrogates
2014
Two new Eu3+ and Au3+ BODIPY-complexes capable of chromofluorogenically detecting micromolar concentrations of V-type nerve agent surrogates by a simple displacement assay are described
Modulating the reaction pathway of phenyl diazonium ions using host–guest complexation with cucurbit[7]uril
2022
Aryl diazonium ions are known to be an important intermediate in the divergent synthesis of azo compounds and substituted aromatics. The presence of more than one electrophilic center in a diazonium ion could lead to undesirable side reactions during a synthesis. Herein, we report that the electrophilic α-carbon on a phenyl diazonium [PhN2]+ ion can be selectively deactivated upon host–guest complexation with cucurbit[7]uril (CB7) in aqueous media, achieving a ∼60-fold increase in the half-life of [PhN2]+. Notably, however, the electrophilic nitrogen of the encapsulated diazonium ion remains active towards diazo coupling with strong nucleophiles, allowing the formation of azo compounds usin…
Increasing the nuclearity and spin ground state in a new family of ferromagnetically-coupled {Ni10} disk-like complexes bearing exclusively end-on br…
2018
The synthesis of a new family of ferromagnetically-coupled {Ni10} clusters counterbalanced by various [Ln(NO3)5]2− ions is herein described. The resulting compounds are organic chelate-free and the metal ions are exclusively bridged by end-on azido ligands to stabilize a beautiful disk-like topology reminiscent of the structure of the brucite mineral.
Photoluminescence quantum yield exceeding 80% in low dimensional perovskite thin-films via passivation control
2017
Quasi-2D perovskites with the BA : MA molar ratio equal to 3 : 3 show a remarkable PLQY exceeding 80%, thanks to the use of an electron donor as the passivating agent. These films have been applied in LEDs that exhibit high brightness exceeding 1000 cd m−2 and current efficiencies >3 cd A−1.
Formation of an unprecedented (CuBr)5 cluster and a zeolite-type 2D-coordination polymer: a surprising halide effect
2013
A unique pentanuclear cluster within a zeolite-type polymer ([Cu5(μ4-Br)(μ3-Br)2(μ2-Br)2](μ2-MeSPr)3)n (1; void space >81%) and a luminescent 1D ([Cu(μ3-I)]4(MeSPr)3)n polymer, 2, are formed when MeSPr reacts with CuBr and CuI.
