Abstract
In this article the author takes upon himself the task of unrolling a local history of organic semiconductors in GERMANY. In doing so, he is well aware of the fact that describing a national development can only highlight isolated spots which are detached from the universal context. A composition of these mosaic stones to reflect the international interrelations of scientific thinking and searching, consisting always of giving and taking at the same time, can only be achieved by a synopsis of all the contributions within this series. In this connection the critical review by Pope and Swenberg1 is worth mentioning which has solved this task for the years until 1980 in an outstanding way; a compressed update of the same authors covers the time until 1983.2 A data compilation of selected experimental results may be found in Reference [85K1].
