Abstract: The study includes the preparation of new dye azo heterogeneous of the ring derived from imidazole of the ligand: 2-[2--(5-Chloro carboxyl Phenyl)azo]-imidazole and the identification of ligand (5-ClCPAI) were identified and analyzed by using 1H-NMR, mass spectrum, FT-IR, UV-Vis, XRD, SEM and EDX. The membranes of ligand prepared of concentration of 0.05, 0.1, 0.3 M membrane pure and doped of 10% ZnO of concentration 0.05 M was prepare of membranes with thikness 1000’10 nm the preparation of membranes by method spray pyrolysis. The study of optical properties of membranes pure and doped study spectral of absorbance and transmittance within the wavelength 200-800 nm, the results show of the transmittance decrease of the molar concentration increase and doped and the absorbance increase with increase molar concentration and doped and energy band gap decrease with increase molar concentration and doping, the study of structure properties of the membranes prepared through (XRD) where the results show membranes multiple crystallization and preferred trend of growth is 101 particle.
