| Abstract | ||
| The derivative of five member heterocyclic ligand containing imidazole rings 4-bromo-2-(4,5-diphenyl-1H-imidazol-2-yl) phenol [Br-HPI] and their complex with Fe(III) are reported. This ligand was characterized by elemental analysis, FT-IR and 1H NMR spectroscopy. The solid complex was characterized by IR spectra, molar conductivity and magnetic moment. The results suggest that the metal is bonded to the ligand through the phenolic oxygen and the pyridine nitrogen forming chelates with (1:2) (metal: ligand) stoichiometry, and the octahedral geometry for the complex. The complex has photolysis by novel method that using UV. cell to synthesis α-Fe2O3 nanoparticles. The nanoparticles have been indicate by transmission electron microscopy (TEM), X-ray diffraction (XRD), scanning electron microscopy (SEM), with average particles size in the range 11 to 25 nm. The α-Fe2O3 nanoparticles have been applied a photo anode to fabrication dye solar cell (ITOα-Fe2O3 Nps odamine 6G dyeAg nanofilmeITO) with energy efficiency conversion about 2.5 %. | ||
