Heterocirculenes as a new class of organic semiconductors†
Abstract
We report a fabrication of field-effect transistors using the new organic semiconductors octathio[8]circulene 5 and tetrathiotetraseleno[8]circulene 6. The maximum hole mobility of 9 × 10−3 cm2V−1 s−1 is, most likely, limited by one-dimensional growth of 5 and 6 in thin films.
