| In this research, we provide the first optical and electrical characterization of 4,6-diacetylresorcinol and 4,6-bis(1-hydrazonoethyl)benzene-1,3-diol. The optical properties have been studied by measuring the diffused reflectance. Both materials have indirect optical transitions with energy gaps of 1.91 and 1.83 eV, respectively. AC electrical conductivity of both materials increases with increasing the applied frequency (1 kHz-5 MHz). It obeys σac(ω)=BωS with S about unity and is explained in terms of correlated barrier hopping model. 4,6-Diacetylresorcinol has higher values of AC conductivity and dielectric constant than those of 4,6-bis(1-hydrazonoethyl)benzene-1,3-diol. Finally, 4,6-bis(1-hydrazonoethyl)benzene-1,3-diol could be employed as a dye to form dye-sensitized solar cells for photosensing applications. |
