Neutral tetrathia[22]annulene[2.1.2.1] based field-effect transistors: Improved on/off ratio defies ring puckering

Article abstract of DOI:10.1039/c2cc37004b

New, neutral, slightly puckered aromatic meso-substituted tetrathia[22]annulene[2.1.2.1] macrocyclic architectures display p-type semiconductor behaviour and constitute molecular field-effect transistors with high on/off ratios (8.67 × 10⁶) and
