SPECTROSCOPIC AND ELECTRICAL-PROPERTIES OF CHARGE-TRANSFER COMPLEXES OF 1,5-DIMETHOXYNAPHTHALENE

The crystalline charge transfer (CT) complexes formed between 1, 5-dim ethoxynaphthalene [1] with some nitroaromatic acceptors of stoichiomet ries 1:1 and 1:2 (donor: acceptor) are reported and discussed using uv -visible diffuse reflectance spectra, infrared spectra and electrical conductivity. The moderately weak interactions are discussed in terms of transition energies electrical conductivities of the complexes and electron affinities of the accepters. Electrical conductivity data rev ealed that the complexes have semiconducting properties. A correlation between the activation energies of conduction with the electron affin ities of the accepters was illustrated.
