Conductivity and photoconductivity properties of multilayer Langmuir-Blodgett (LB) films of corbathiene (similar to 100 nm thick) have been investigated. The conductivity exhibits anisotropic behaviour, i.e. it is different for lateral and transverse directions. Measurements of lateral photoconductivity and its dependence on wavelength and intensity of exciting light have been performed. The time-resolved decay of the photoinduced conductivity is indicative of more than one recombination mechanism. The results are related to the optical absorption features and discussed in terms of semiconducting concepts. Lateral photoconductivity has been found to be essentially a bulk property of the films. All data obtained are well reproducible which means that the LB corbathiene films are stable at room temperature in the current density range investigated (10(-7) to 10(-6) A cm(-2)) when subjected to illumination in the wavelength range 300-900 nm (10(16)-10(17) photons cm(-2) s(-1)).
