Abstract A novel and effective phthalazine-imidazole-based colorimetric chemosensor (E)-1-(2-((1H-imidazol-2-yl)methylene)hydrazinyl)phthalazine NNI was synthesized and tested to detect Cu2+ or Co2+ ions in buffer solution. NNI could probe Cu2+ and Co2+ by the color change from colorless to yellow. The complexation stoichiometries of NNI toward Cu2+ and Co2+ were, respectively, confirmed to be as 1 : 1 ratio and 2 : 1 by results of Job plot and ESI-mass. Detection limits of NNI for each metal sh...

Abstract The new ligand H2L, constituted by a tetraethylenepentamine terminally functionalized with terminal 6-amino-3,4-dihydro-3-methyl-5-nitroso-4-oxopyrimidine groups, has been synthesized with the ultimate goal of preparing Pd2+-containing heterogeneous single metal ion catalysts based on multi-walled carbon nanotubes (MWCNT-L-Pd) and graphene (G-L-Pd) for catalytic applications. In this paper, we report the synthesis of the ligand and a preliminary characterization of its coordination prop...
Abstract The utilization of a Schiff-base ligand (E)-1-(((2-(hydroxymethyl)phenyl)imino)methyl)nap- hthalen-2-ol afforded two 3d-4f hexanuclear complexes of formula [CoIII2LnIII4(μ3-OH)2(NO3)4 (OAc)4L4(DMF)2]·2C2H5OH [Ln = Dy(1), Gd(2)]. Single-crystal X-ray diffffraction analysis revealed that complexes 1 and 2 were isomorphous and had a chair-like topology. The core was composed of a defect-dicubane Ln4 moiety, which were supported by two μ3-OH groups. Two CoIII ions flanked the Ln4 core with ...

Abstract In the present work we obtained a series of NIR luminescent platinum(II) complexes with a pincer N^N^C ligand based on the conjugated {benzo [4] , [5] imidazo[1,2-a]pyrazine} system with the [Pt(N^N^C)L]n+ structural motif (L = phosphine, alkynyl or pyridine-type ligands). We have also synthesized two complexes with bidentate phosphines that demonstrate different types of coordination: 1) as chelating ligand (in case of 1,2-bis(diphenilphosphino)benzene), that led to de-coordination of ...

Abstract A series of chiral organozinc complexes [(L1)ZnEt]2 (1), [(L2)ZnEt]2 (2) and [(L3)ZnEt]2 (3) have been prepared by ethane elimination reaction between ZnEt2 and the corresponding chiral sulfonylamidoazetidine ligands, (1’S,2S,3S)-1-(1’-Phenylethyl)-2-phenyl-3-isopropylsulfonamidoazetidine (HL1), (1’S,2S,3S)-1-(1’-Phenylethyl)-2-phenyl-3-(p-tolylsulfonamido)azetidine (HL2), and (1’S,2S,3S)-1-(1’-Phenylethyl)-2-phenyl-3-(m-tolylsulfonamido)azetidine (HL3), respectively. These complexes we...

Abstract To develop novel fluorescent probes for detecting endogenous histidine (His) plays significant roles in physiological and pathological fields. Herein, a non-emissive Ir(III) complex [Ir(C-N)2(CH3CN)2]+NO3- (IrCN, C-N represents 2-phenylpyridine derivative) has been demonstrated to be a reaction-based fluorescent probe for the recognition of His in HEPES buffer. It is found that IrCN can selectively detect His with a distinct “turn-on” luminescence and low limit of detection (LOD = 0.62 ...

Abstract The reaction of mercury(II) iodide and potential tetradentate ligand N-(2-pyridylmethyl)iminodiethanol (H2pmide) or N,N-bis(2-pyridylmethyl)-2-aminoethanol (bpaeOH) leads to the isolation of monomeric complex [Hg(H2pmide)(I)2] (1) and tetrameric {[Hg2(bpaeOH)2][Hg2I7]I} (2). The crystal structures of 1 and 2 have been characterized by single crystal X-ray crystallography. In mononuclear neutral complex 1, the Hg(II) ion is bonded with one H2pmide species and two iodide anions as a disto...
