[C–H⋯anion] interactions mediate the templation and anion binding properties of topologically non-trivial metal–organic structures in aqueous solutions
Bilbeisi, Rana A.; Prakasam, Thirumurugan; Lusi, Matteo; El-Khoury, Roberto; Platas-Iglesias, Carlos; Charbonnière, Loïc J.; Olsen, John-Carl; Elhabiri, Mourad; Trabolsi, Ali (Royal Society of Chemistry, 2016-02-12)[Abstract] Two synthetic approaches—temperature variation and anion templation—allowed for the selective formation of a [2]catenane ([2]C4+) or a trefoil knot (TK6+), or for the enhanced formation of a Solomon link (SL8+), ... -
Highly relaxing gadolinium based MRI contrast agents responsive to Mg2+ sensing
Abada, Sabah; Lecointre, Alexandre; Elhabiri, Mourad; Esteban-Gómez, David; Platas-Iglesias, Carlos; Tallec, Gaylord; Mazzanti, Marinella; Charbonnière, Loïc J. (Royal Society of Chemistry, 2012-04-28)[Abstract] A Gd complex based on a polyphosphonated pyridyl ligand shows a very high stability in aqueous solution (logKEuL = 25.7), a high relaxivity (8.5 mM−1 s−1 at 25 °C and 20 MHz) and a marked and selective relaxivity ... -
Importance of outer-sphere and aggregation phenomena in the relaxation properties of phosphonated gadolinium complexes with potential applications as MRI contrast agents
Elhabiri, Mourad; Abada, Sabah; Sy, Mohamadou; Nonat, Aline; Choquet, Philippe; Esteban-Gómez, David; Cassino, Claudio; Platas-Iglesias, Carlos; Botta, Mauro; Charbonnière, Loïc J. (Wiley, 2015-04-10)[Abstract] A series composed of a tetra-, a tris- and a bisphosphonated ligand based on a pyridine scaffold (L4, L3 and L2, respectively) was studied within the frame of lanthanide (Ln) coordination. The stability constants ... -
Sulphur-rich functionalized calix[4]arenes for selective complexation of Hg2+ over Cu2+, Zn2+ and Cd2+
Bensenane, Bachir; Asfari, Zouhair; Platas-Iglesias, Carlos; Esteban-Gómez, David; Djafri, Fatiha; Elhabiri, Mourad; Charbonnière, Loïc J. (Royal Society of Chemistry, 2016-08-16)[Abstract] The syntheses of two new ligands based on a calix[4]arene scaffold in the cone conformation functionalized on the phenolic positions 1 and 3 by diethylthiophosphonates (L1) or tetra(tri)thioethyleneglycol (L2) ... -
Tuning the copper(II) coordination properties of cyclam by subtle chemical modifications
Camus, Nathalie; Le Bris, Nathalie; Nuryyeva, Selbi; Chessé, Matthieu; Esteban-Gómez, David; Platas-Iglesias, Carlos; Tripier, Raphaël; Elhabiri, Mourad (Royal Society of Chemistry, 2017-09-14)[Abstract] The acid–base and copper(II) coordination properties of three previously described cyclam derivatives are reported. Potentiometry, mass spectrometry, UV-vis absorption spectroscopy, electrochemistry and theoretical ... -
Viologen–cucurbituril host/guest chemistry – redox control of dimerization versus inclusion
Dalvand, Parastoo; Nchimi Nono, Katia; Shetty, Dinesh; Benyettou, Farah; Asfari, Zouhair; Platas-Iglesias, Carlos; Olson, Mark Anthony; Trabolsi, Ali; Elhabiri, Mourad (Royal Society of Chemistry, 2021-09-02)[Abstract] Two calix[4]arene systems, C234+ and C244+ – where 2 corresponds to the number of viologen units and 3–4 corresponds to the number of carbon atoms connecting the viologen units to the macrocyclic core – have ...
