间隔试剂调控的分子聚集体——过渡金属配位砌块的组装

1.Supramolecular complexes constructed by dicopper oxamidato building blocks: the antiferromagnetic coupling effects were studies for inter-building blocks, which provides important information on future design and modification of ferromagnetic materials;2.Cluster complexes containing mixed phosphine and thiolates: bidentate phosphines were employed to control the fabrication of silver coordination complexes, novel structures were obtained for a series of discrete cluster complexes and coordination polymers. 31P NMR studies also showed a novel case of Ag-P coupling effect in a disilver complex containing tripodal igand;3.Supramolecular complexes of bi- or tri-armed N-containing ligands: structural analyses on several different series of complexes showed that the oxidation state, the d electron number, the anion, the solvent, and the spacer within the ligand between chelating groups are all important factors which can control and modulate the construction of molecular structures.4..Bivalent transition metal complexes of 4,5-diazofluorenone hydrazones: several series of transition metal complexes coordinated by different hydrazones were synthesized which were studied by 1H NMR to show whether it is enol or keto ligation, results also explained the screening effect of the imino-nitrogen atom on the chemical shifts of attached protons.

选择适当小分子或离子为间隔试剂，利用过度金属为砌块，结合超分子合成子所形成的分子间弱作用力，进行分子组装，构筑在光、电、磁等方面有特殊功能的有序分子聚集体，为新颖超分子物质合成提供新途径。以之为新型材料，进一步提供超分子器件的研制。同时，在理论上将分子内协同效应的概念应用到分子间隔弱作用力的阐述。有重大社会效益。.
