The luminescent quenching of coordination polymers 1 and 2 were especially obvious with the increasing of the nitro derivatives concentration, indicating 1 and 2 have very high sensitivity sensing properties.
Two vanadium(iii) complexes were synthesized. Hydrogen peroxide was detected by a colorimetric method based on catalytic bromination reactions with the complexes as catalysts.
The complexes [Co(bdpdt)(dipic)]Á3H 2 O (1) and [Ni(bdpdt)(dipic)]Á3H 2 O (2) (bdpdt: 2,4-bis(3,5-dimethyl-1H-pyrazol-1-yl)-6-diethylamino-1,3,5-triazine, H 2 dipic: 2,6-pyridinedicarboxylic acid) were synthesized by the reactions of CoCl 2 or NiCl 2 with bdpdt and H 2 dipic in mixed water-ethanol solution at 120°C. The complexes were characterized by elemental analysis, IR spectroscopy, UV-Vis spectroscopy and single-crystal X-ray diffraction. Thermogravimetric analysis showed that both complexes are stable up to 300°C. Structural analysis reveals that the Co(II) and Ni(II) atoms both have distorted octahedral geometries. The catalytic performances of both complexes for the oxidation by H 2 O 2 were studied at room temperature. Graphical Abstract Two complexes containing pincer N-heterocyclic ligand and H 2 dipic were synthesized. All the complexes were characterized by elemental analysis, IR spectroscopy, UV-Vis spectroscopy and single-crystal X-ray diffraction. In addition, the catalytic performances of complexes 1 and 2 were also studied on the oxidation reaction of cyclohexane at room temperature.
We synthesized three novel d7/d10 metal complexes with 2,6-bis(3-pyrazolyl)pyridine and studied their surface photovoltage spectra and photocatalytic activities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
