A new stable solid di[1-(2-ethoxyethyl)-5-nitrobenzimidazole] cobalt dichloride (2) and di[1-(2-ethoxyethyl)-5-nitrobenzimidazole] copper dichloride (3) were prepared by the combination of 1-(2-ethoxyethyl)-5-nitrobenzimidazole (1) with metal salts (CoCl₂.6H₂O and CuCl₂.H₂O). Synthesized di[1-(2-ethoxyethyl)-5-nitrobenzimidazole] cobalt dichloride (2) and di[1-(2-ethoxyethyl)-5-nitrobenzimidazole] copper dichloride (3) were identified by ¹H NMR and ¹³C NMR spectroscopic techniques and elemental analysis. Poly vinyl alcohol (PVA) polymer with and without novel benzimidazole cobalt and copper complexes dopant interfacial layers were used in Au/n-Si diodes. The basic electrical properties of these fabricated four diodes were examined using current-voltage (I–V) measurements in dark and room temperature. The n and I₀ values of all MPS diodes are smaller than the MS diode and the Φ_B0 values are greater.
