The role of H-bonds in the solid state organization of [1]benzothieno[3,2-b][1]benzothiophene (BTBT) structures: bis(hydroxy-hexyl)-BTBT, as a functional derivative offering efficient air stable organic field effect transistors (OFETs)

Abstract

The rapid and inexpensive functionalization of the BTBT core with hydroxyl end group functionalized hexyl chains offered a new platform for functionalized self-organising BTBT.
