The synthesis of D-π-D derivated phthalocyanines for dye-sensitized solar cell, investigation of spectroscopic and electrical properties

Recently the phthalocyanine compounds both in the scientific intense interest in attracting industrial applications, impressive color they have, of the phthalocyanine ring 18 π electron system, a variety of substituents in non-peripheral or peripheral location and the center is due to the different characteristics of the metal cation. All these features provide interesting optical properties. In addition, structural and coordination due to the properties of light emitting diodes (LEDs), solar cells, electrocatalysts are, electrochromic devices, which find use in many areas, such as the possibility of photosensitiser with. Solar cells based on organic materials (dsscs) materials are used in a wide variety of paint feature class. Porphyrins, porphyrazines, phthalocyanines, polipirid, coumarins, indolines, triphenylamine days, conjugated polymers, fluorene is located in these classes. These substances, they have higher the absorption coefficient in the region appear electronically (ε> 105 M-1cm-1) is very important. In this thesis of 4-(Diphenylamino) benzaldehyde containing substituents D-π-D features new nickel, cobalt, ruthenium and zinc phthalocyanine synthesis was performed complex. Besides other important properties of the synthesized compounds it was found to have application for dsscs high molar absorption coefficient. Electron-donor molecules (D) and other electron donating triphenylamine as a group (D) are group's phthalocyanine. This material enables the movement of electrons in the π-conjugation are the imine group. The structure of all synthesized complex, elemental analysis, FTIR, UV-vis, H-NMR and MS were illuminated with fluorescence. In addition, to solar cell production and characterization of the coated material on ITO in the darkness before the light conditions then current battery voltage measurements were performed.
