Using the time subordinate thickness utilitarian theory, we moved in this work the electronic osmosis spectra of a movement of heteroleptic buildings the construction [M(dppf)L] [where dppf =1,10-bis(diphenylphosphino) ferrocene, M=Pt and L= p-tolylsulfonyl dithiocarbimate, p-CH3 C6H4 SO2 NCS2 (1). M=Pt and L= p-chlorobenzene sulfonyl dithiocarbimate, p-ClC6 H4 SO2 NCS2 (2). M=Pt and L= p-bromobenzene sulfonyl dithiocarbimate, p-BrC6 H4 SO2 NCS2 (3). M=Pt and L= 1-ethoxycarbonyl-1-cyanoethylene-2,2-dithiolate(ecda). These structures have been coordinated and depicted probably using the spectroscopy procedures (IR, 1H, 13C and 31P NMR and UV-Vis) and valuable stone X-bar diffraction. Due to their photo physical and photochemical properties, they have been used as photo sensibilisator in the DSSC (Dye Sensitized Cell Solar). The change adequacy of DSSC is described by the limit of the electron transport, unobtrusive production, versatility and remarkable maintenance in the clear area of the reach. To notice tones satisfying these constraints, various exploratory researches have been done to coordinate and to inspect different molecules.
