New sulfur bridged neutral annulenes. Structure, physical properties and applications in organic field-effect transistors†
Abstract
New, neutral, meso-substituted tetrathia[22]annulene[2,1,2,1] aromatic macrocyclic architectures display p-type semiconductor behaviour and constitute efficacious molecular field-effect transistors with reproducible bulk-like carrier mobility (as high as 0.63 cm2 Vā1 Sā1) on highly crystalline thin films deposited on
