Organic pigments such as phthalocyanines (I), naphthalocyanines (II), and diimides of perylenetetracarboxylic acid (III) are of basic as well as application-related interest due to their electric and photoelectrical properties. Presently there is a great interest in photovoltaic as well as photoelectrochemical devices in which the materials behave like classical semiconductors. Quite a number of derivatives of the mentioned classes of materials could be synthesized, showing strongly differing junction properties. In this study thermoelectric power measurements were performed at annelated tetraazaporphyrins as well as 3,4,9,10-perylenebis(dicarboximides). 50 refs., 1 fig., 1 tab.
