Chemosensors based on indicator displacement were developed for the optical detection of different analytes in aqueous solution. The sensing of carbohydrates, including glucose, in aqueous solution at pH 7.4 was achieved by a fluorescent indicator displace ...
Hexanuclear coordination cages of the formula [(C5Me4R)M(C7H3NO 4)]6 (M = Rh, Ir; R = Me, H) were obtained by stepwise reaction of [(C5Me4R)M(μ-Cl)Cl]2 with, first AgOAc and then pyridine-3,5-dicarboxylic acid. Crystallographic analyses show that the cages ...
The synthesis, structure, and reactivity of a new complex of U(IV) with the tridentate Schiff base ligand Menaphtquinolen are reported. The reduction of the bis-ligand complexes [UX2(Menaphtquinolen) 2] (X = Cl, (1-Cl); I (1-I)) with potassium metal afford ...
A facile method to coordinate transition metal complexes (TMCs) on single-walled carbon nanotubes (SWNTs) has been developed. Reaction of Zn(OAc)2 with carboxylic acid functionalized SWNTs (SWNT-COOH) affords SWNT complexes zipped-together' by zinc carboxy ...
Chiral trivalent phosphorus species are the dominant class of ligands and the key controlling element in asymmetric homogeneous transition-metal catalysis. Here, novel chiral diaminophosphine oxide ligands are described. The arising catalyst system with ni ...
Ru-II(arene) complexes of the general formula [Ru-II(eta(6)-p-cymene)(PPh3)(L)Cl]PF6 with L = P- or N-donor systems have been synthesized and characterized. Carbohydrate-derived phosphites, imidazole or indazole have been chosen as co-ligands and different ...
Mn2+ complexes represent an alternative to Gd3+ chelates which are widely used contrast agents in magnetic resonance imaging. In this perspective, the authors studied the Mn2+ complexes of two 12-membered, pyridine-contg. macrocyclic ligands bearing one pe ...
Two tridentate pyridine-tetrazolate ligands (H 2pytz and H 2pytzc), analogues of the well-known dipicolinate (H 2dpa) ligand, have been synthesized in a straightforward manner and used for lanthanide(iii) coordination. The structures of the resulting tris- ...
The formation of either dinuclear double-stranded or pentanuclear circular helicates from a ligand containing two tridentate domains separated by a phenylene unit can be controlled by inter-ligand steric interactions which themselves are governed by the si ...
A cyclic tetranuclear cyclometallated iridium(III) complex using cyanide anions as bridging ligands and displaying a tetrahedrally distorted square geometry has been obtained with high yield; photo- and electrochemical characterizations show that most inte ...
