Applications Of New Type Of Zinc Porphyrin Axial Coordinate Self-assembly In Supramolecular Solar Cells

Porphyrin and its compounds have a macrocyclic conjugated structure.Because of this unique structure and its excellent properties, it is widelyapplied in the field of medicine, materials science, electrochemistry,analytical chemistry and so on. Since the characteristic of low pollutionand cost, porphyrin that is widespred in nature has been used ofdye-sensitized solar cells (DSSCS). Meanwhile, through self-assemblytechnology, via of the non-covalent interaction, molecules polymerize toa stable structur, complex and orderly aggregation body spontaneously. Inrecent years, as cross fields among organic chemistry, inorganic chemistry,analytical chemistry, biochemistry and medicine science, thesupramolecular self-assembly function of porphyrin has broadlyprospects in terms of high-performance materials. The self-assemblytechnology can develop new study prospects of porphyrinsupramolecular.Schiff bases and Acylhydrazone both have C=N double bond group,these organic compounds have a strong coordination ability. IntroducingC=N double bond into porphyrin’s meso-position, it can greatly improvethe light emitting performance of entire Porphyrin molecules, thusimproving photoelectric conversion efficiency of solar cell. N-heterocycle(Imidazole, Tetrazole) which has strong fluorescence properties couldenhance porphyrin photoelectric performance. Utilizing these compoundsof porphyrins in solar cells has been studied seldom, this thesis focus onthe supramolecular self-assembly applications in the field of solar cells.This thesis includes the following aspects:1. Studying the spectral quality of new A4types of Schiff base zincporphyrin compounds and its photoelectric conversion efficiency,understanding the application of supramolecular self-assembly function in solar cells.2. Studying the spectral quality of new A4types of meso-tetra-benzamide znic porphyrin compounds and its photoelectric conversionefficiency, understanding the application of axial coordinationself-assembly function in solar cells.3. Studying the spectral quality of meso-position N-heterocyclicsubstituted znic porphyrin compounds and its photoelectric conversionefficiency, understanding its application in solar cells.
