Synthesis of nanoparticles of a new coordination complex bearing a phosphoramide ligand designed for application in dye sensitized solar cells

In this study, using ultrasonic method, nanoparticles of a new phosphoramide compound and its cobalt nitratecomplex with formula L = (4-NO2-C6H4NH)P(O)Cl(NH-C5H4N-2) (1) and Co(NO3)2(L)(CH3OH) (2) were synthesizedand characterized by 31P, 1H, 13C NMR, FT-IR, UV-Vis, fluorescence spectroscopy and elemental analysis as well as FESEMand XRD techniques. The FE-SEM analysis showed that particle sizes of the compounds 1 and 2 are about 20-50nm. The compounds 1 and 2 were utilized as dyes for absorbing light in dye sensitized solar cells and the efficiencies ofthe cells were obtained equal to 0.42 and 0.49% respectively.
