Synthesis And Properties Of New Porphyrin - Schiff Base, Porphyrin Dimer And Metal Compounds

Porphyrins represent an extremely important class of molecules with promising application potentials in many areas of scientific research. The unique optical and electronic properties of porphyrins, such as strong absorption and emission in the visible region, semiconductivity, and strong photoelectrochemical activity, have attracted extensive attention in applications in the areas of photoelectronic devices, chemical sensors, catalysis, and molecular electronics.The thesis is mainly about the synthesis and characterization of two kinds of porphyrin compounds. It is composed of three parts: the first chapter is about the summarization of the research status of porphyrin compounds, especially the introduction of its synthesis and application. The second chapter mainly discusses the six metal compounds of porphyrin-Schiff base, which were characterized by FT-IR, UV-Vis spectra and 1H NMR. Furthermore, one of the target compounds was confirmed by single crystal X-ray diffraction. In addition, the thermostability and luminescent effect of the target compounds were studied. The experiment shows that the strongest luminescent wavelength is 600nm, which locates in visible light area. The compounds decompose at 70℃in the air. The third chapter was about a kind of binuclear porphyrin and its copper and zinc complexes. The structures of the above synthetic products were characterized by IR, UV-vis, 1H NMR. The spectra data of these new complexes, metal complexes were assigned. The spectra influence of different metal on the same ligand were discussed and explained.
