Chalcogen-substitution modulated supramolecular chirality and gas sensing properties in perylenediimides

Abstract

We present the modulation of van der Waals interactions to further adjust supramolecular chirality by incorporation of S and Se into the bay region. These chalcogen atom-mediated supramolecular interactions were transferred to nanostructures and affected the gas responses of devices. This study will facilitate the development of smart materials with modulated handedness in materials science.
