Syntheses, Structures And Marine Microorganism Inhibitory Activities Of Flexible Ligands Containing N, O Or S Heteroatoms And Their Metal Complexes

Ligands containing N,O, or S heteroatoms, and their metal complexes possess significant theoretical values and application values in biology, material and catalysis fields due to their excellent biological activities. In this work, a series of flexible ligands with heterocyclic compounds as functional groups and their metal complexes were designed, synthesized and characterized by elemental analysis, IR,1H NMR, electrochemistry and thermogravimetric analysis. Marine microorganism inhibitory activities of these compounds have been studied in detail.1. Studies and applications of the coordination polymers and the metal complexes with heterocyclic ligands were concisely introduced in biology, material and catalysis fields. The aim as well as the significance of this work has been outlined.2. An aminepyridine derivative, bis(2-(pyridin-2-ylthio)ethyl)amine, and its metal complexes was designed and synthesized. Crystal structure of the ligand was studied. Marine microorganism inhibitary activities of ligands and metal complexes were investigated.3. A oxazolidinone derivative,3-[2-(1,3-benzothiazol-2-ylsulfanyl)ethyl]-1,3-oxazolidin-2-one, was designed and synthesized. Single crystal X-ray diffraction analysis of the ligand was undertaken. Marine biological activitivities of ligands and corresponding metal complexes were studied.4. A pyrimidine compound, bis(2-(4,6-dimethylpyrimidin-2-ylthio)ethyl)amine, was designed and synthesized. Crystal structure of the ligand was studied. Marine microorganism inhibitary activities of ligands and metal complexes were investigated.5. Open chain crown ethers containing pyrithione groups were designed and synthesized. Marine biological activitivities of ligands and corresponding metal complexes were studied.
