A Facile PDMS‐Assisted Crystallization for the Crystal‐Engineering of C₆₀ Single‐Crystal Organic Field‐Effect Transistors

Abstract

Poly(dimethylsiloxane) (PDMS)-assisted crystallization (PAC) is a facile method to produce oriented C60 crystal arrays. Changing the drying mechanism from evaporation to solvent absorption (by PDMS) widens the solvent selection and facilitates the engineering of both the macroscopic shape and the microscopic lattice structure of the crystal arrays. The method also shows the potential to be applied to other organic semiconductors and large-area production.
