From co-crystals to functional thin films: photolithography using [2+2] photodimerization†
Abstract
An approach to form organic thin films that employs multicomponent solids in the form of co-crystals has been developed. The components direct an intermolecular [2+2] photodimerization that we demonstrate exhibits a change in solubility that can be exploited as a negative photoresist for use in photolithography.
