Abstract: | Summary Results of experiments on dark- and photoconductivity of polymeric dibenz[b,i] 1,4,8,11-tetraaza[14]annulenato( -pyrazin) iron(II) [Fetaa(pyz)]n are described. By studying the dependence of photoconductivity on electric field, intensity and wavelength it is shown that photogeneration of charge carriers occurred at short wavelengths by an Onsager mechanism and in the near-infrared region by a photoinjection process from the electrodes.Dedicated to Prof. Dr. G. Manecke on the occasion of his 70th birthdayThe authors would like to thank the Volkswagen Foundation for financial support. |
