DARK AND PHOTOCONDUCTIVE PROPERTIES OF HYDROXYMETHYLFERROCENE

The dark electrical conduction properties of hydroxymethylferrocene ha ve been studied as a function of voltage at different sample cell temp eratures by using sandwich-cell configuration. The analysis of the res ults has been based on the space charge limited conduction (SCLC) theo ry. The distribution of traps in this material has been found to be si ngle discrete level type. Photoconductivity in this material has been studied as a function of the intensity of exciting light source (mercu ry lamp; 125 W) and sample cell temperature. The results have been com pared with the results of ferrocene and, in some cases, with other fer rocene derivatives. An unusual temperature-dependence of photocurrent has been observed. The possible origin of this observation has been di scussed. (C) 1998 Elsevier Science S.A. All rights reserved.
