Abstract
WE have investigated the dark- and photo-conductivity of single crystals of metal-free and some transition metal phthalocyanines. Some of our results for metal-free, zinc, copper, nickel and cobalt phthalocyanines have been published elsewhere1. Meanwhile we have extended our investigations to include ferrous and manganous phthalocyanines. Here we wish to report briefly that we have found manganous phthalocyanine to differ in its behaviour from the other members of the series in a striking manner. The measurements were made on the needle-shaped crystals using two electrodes. No guard ring was used, and the arrangement is therefore equivalent to a surface conductivity cell.
