Two novel fluorescent probes based on triphenylamine (TPC) and phenanthro(9,10-d-imidazole) (PITP) have been synthesized and studied as cyanide selective indicators in aqueous media. Complete colour bleaching was observed due to the nucleophilic addition of cyanide to the 2-vinylmalononitrile of TPC, which results in the disruption of the extended conjugation and turns off the intramolecular ch...

The title compound, [Mn6(C7H4NO3)5(CHO2)2(C3H4N2)5(CH3OH)]·3.36CH3OH·0.65H2O, or Mn(II)(O2CH)2[15-MCMn(III)N(shi)-5](Im)5(MeOH)·3.36MeOH·0.65H2O (where MC is metallacrown, shi(3-) is salicyl-hydroximate, Im is imidazole and MeOH is methanol), contains five Mn(III) ions as members of the metallacrown ring and an Mn(II) atom bound in the central cavity. The central Mn(II) atom is seven-coordinate...

We report a novel ruthenium(II) complex for selective release of the imidazole-based drug econazole. While the complex is highly stable and luminescent in the dark, irradiation with green light induces release of one of the econazole ligands, which is accompanied by a turn-off luminescence response and up to a 34-fold increase in cytotoxicity towards tumour cells.

Abstract A new method to synthesize complexes of the type [(CNC)Ru II (NN)L] n+ has been introduced, where CNC is a tridentate pincer composed two (benz)imidazole derived NHC rings and pyridyl ring, NN bidentate aromatic diimine ligand, L=bromide or acetonitrile, n=1 2. Following this series six synthesized characterized by spectroscopic, analytic, crystallographic, computational methods. Their...

In the coordination polymer, [Cu(I)(C(13)H(11)N(2)O(2))](n), the Cu(I) atom exists in a trigonal-planar geometry that is defined by the C=C unit, the imidazole N atom and carboxyl-ate O atoms from three different ozagrel ligands, resulting in the formation of a three-dimensional framework.

The 5-amino-(cyanoformimidoyl)-1H-imidazole has been prepared from amidine by treatment with barium hydroxide in ethanol. 2-(4-Isopropylbenzyl)-6-carbamoyl-1, 2-dihydropurine was obtained from 5-amino-4-(cyanoformimidoyl)-1H-imidazole and isopropylbenzaldehyde in dry methanol. All compounds have been fully characterized by spectroscopic data.
