Organic single-crystalline transistors based on Benzo[b]thiophen-Benzo[b]furan analogues with contorted configuration

Four novel benzo[b]thiophene-benzo[b]furan analogues with contorted configuration were synthesized and exhibited good solubility in normal solvents. Mobility over 0.8 cm2V−1s−1 could be achieved for the single-crystalline field effect transistor. The important effect of hydrogen bonding on the structure and properties relationship of the organic π-conjugated molecules was verified by X-ray crystallography, optical, electrochemical characteristics and DFT calculations.158
