Synthesis of organosilicon derivatives of [1]benzothieno[3,2-b][1]-benzothiophene for efficient monolayer Langmuir–Blodgett organic field effect transistors

Abstract

For the first time, the synthesis of organosilicon derivatives of dialkyl[1]benzothieno[3,2-b][1]-benzothiophene (BTBT) capable of forming a semiconducting monolayer at the water–air interface is reported. Self-assembled monolayer organic field-effect transistors prepared from these materials using the Langmuir–Blodgett technique showed high hole mobilities and excellent air stability.
