BTQBT (bis-(1,2,5-thiadiazolo)-p-quinobis(1, 3-dithiole)) thin films; A promising candidate for high mobility organic transistors

BTQBT (bis-(1, 2, 5-thiadiazolo)-p-quinobis(1, 3-dithiole)) Films have been prepared as active semiconducting layers of organic field effect transistors (FETs). BTQBT films showed a p-type semiconducting behavior. The hole mobility and on/off ratio of BTQBT films under ultrahigh vacuum conditions reached to 0.2 cm-(2)/V(.)s and 10(8), respectively. by optimization of the growth conditions. These values are in the same order as those of pentacene thin films. which indicates that BTQBT molecules have a great potential for active layers of organic electronic devices.
