Design Of Fluorescence Probe And Study Of Catalytic Asymmetric Reaction On O-Hydroxyl Aldehyde

This thesis is mainly aimming at studying on the applications of fluorescence probe and catalytic asymmetric of multifunctional ligand based on o-hydroxyl aldehyde,and discussing the ligand which have the selectivity to some ions.It is composed of four parts:1.The background of this work is concisely introduced with the emphasis on the current survey of Schiff base which is relevant to the thesis,The theory about the luminescent lanthanide complexes and the fluorescence probe was given.2.The ligands of Schiff base based on the naphthoic aldehyde and their complexes were synthesized and characterized.Two ligands were synthesized based on the naphthoic aldehyde,the results show that they were good fluorescence probes for Y³⁺ or Zn²⁺.The compositions and structures of the complexes were determined and characterized by IR,elemental analysis,UV-Vis,NMR,X-ray diffraction etc.The mechanism of selectivity was also studied.3.Sensitization and fluorescence probe of Schiff base of open chain crown ether was preliminarily studied,a series of open chain crown ethers based on the salicylaldehyde were synthesized,the ligands have some fluorescence properties, which were good selective to the Mg²⁺ or can sensitize Tb³⁺.4.The chiral amino alcohol based on the naphthoic aldehyde was used in the asymmetric borane reduction of prochiral ketones.The high ee value were obtained up to 87%,and the unusual temperature dependent reversal of stereoselectivity was observed,which is not been seen commonly.
