RefatDepartment of Chemistry, Colloge of Education, Imam Abdulrahman Bin Faisal University, Dammam 1982 , Saudi ArabiaAbstract The main task of this article was to prepared of new pigment model in situ solar cells accordance tocharge-transfer complexes of rhodamine C (RhC) donor as dye laser gain media with iodine (-acceptor) and

chloranilic acid, CLA (^-acceptor). The synthesis stoichiometry of these complexes were of 1：2 (donor : ac-

ceptor) with general formulas [(RhC)* ? I3 and )(RhC) (CLA) * The discussed data of elemental analysis, conductivity measurements, FT-IR, UV-Visspectroscopyandphotometrictitrationdatavisualizedthestoichi-
