Studies On Synthesis And Application Of Ruthenium Complexes Based On Nitrogen-Containing Ligands

Nitrogen-containing ligands are widely used in the synthesis of complexes and organometallic compounds due to their strong coordination ability and easy modification.There are more and more reports about organometallic complexes formed with ruthenium metal.In this paper,starting from different nitrogen-containing ligands,two types of organometallic complexes with ruthenium as the metal center were synthesized,and their applications in catalytic hydrogenation and anion recognition were studied.main tasks as follows:1)Using[(p-cymene)RuC12]2 with a series of Schiff bases with different substituents[N,O]-chelated to obtain a ruthenium organometallic complex with a semi-sandwich structure.These ruthenium metal complexes with different substituents have high catalytic activity for the catalytic hydrogenation of ketone alkane or nitroalkane,with TON reaching 960 and 1960 respectively,and exploring the effects of electronic and steric hindrance effects on catalytic efficiency;2)A simple molecular fluorescent Ru(?)probe was synthesized by reacting 5-aldehyde-2,2'-bipyridine with ruthenium(?)chloride under mild conditions.In the aqueous phase(40%CH3CN/60%H2O),the complex achieves high sensitivity and selective recognition of cyanide ions.The detection limit is 0.75 ?M,and the color of the solution changes from orange to light yellow quickly,enabling naked eye recognition..According to the color change of the solution,a visible colorimetric test strip was prepared.The test strip has the characteristics of fast response time and obvious color change for the detection of cyanide ions.
