| Summary: | 碩士 === 淡江大學 === 化學學系碩士班 === 96 === In this research, a series of new ligands containing hydrazone and derivative naphthyridine moiety were synthesized successfully, after complexed with binding Zn (II) , gives sandwich like complexes , namely, [Zn2(C2-Me-(Dmenpt)2)2(OH)2(CH3OH)2](ClO4)2 1 、[Zn2(C2-H-(Dmenpt)2)2(OH)2(H2O)2](ClO4)2 2 ，and planar structure ，[Zn(Py-Me-(Dmenpt)2)(CH3OH)2](ClO4)2 3 、 [Zn(C2-Me-(Npt)2)(CH3OH)2](ClO4)2 4， and complexes with silver(I) to formed tetranuclear helicate , namely, [Ag4(C2-Me-(Npt)2)2](CF3SO3)4 5 .The crystal structures of the complexes have been determined by X-ray analysis﹐and ESI-Mass spectrometry proved a very useful characterisational tool in detecting the distribution of complexes in solution﹐the results confirmed the solid state is maintained in the solution state.
The self-assembling and self-recognition process were studied by UV-Vis titration, and were investigated by means of systematic measurement of step-wise and overall stability constant .
We present molecular self-assembly system﹐driven mostly by π-π interactions﹒The formation of such self-organization is characterized with absorption and fluorescence spectroscopies﹒Our results demonstrate that molecules can promote self-organization in solution.
The flourescence spectra of ligands and complexes haved been investigated.
