Enhancing the Thermal Stability of Organic Field-Effect Transistors by Electrostatically Interlocked 2D Molecular Packing

Abstract

A study was conducted to enhance the thermal stability of organic field-effect transistors (OFETs) by electrostatically interlocked 2D molecular packing. The investigation was based on single-crystal field-effect transistors (SCFETs) comprising two distinct polymorphs of 2,8-bis(butyl(methyl)amino)indeno[1,2-b]fluorene-6,12-dione (BMA-IFD). The thermal stabilities of the two polymorphs were investigated by the differential scanning calorimetry (DSC). The α-phase polymorph showed two exothermic peaks around 157 and 168 °C during heating and an endothermic peak around 66 °C during cooling.<br/>
