Room temperature chiral reorganization of interfacial assembly of achiral double-decker phthalocyanine

Author affiliations

Abstract

The modulation of solid-state supramolecular assemblies at room temperature is still challenging even though it potentially has very important application prospects. Herein, based on the possibility of overall conformational changes in double-decker phthalocyanine, the room temperature chiral reorganization of solid-state assemblies was investigated. LS (Langmuir–Schaefer) films of achiral double-decker cerium phthalocyanine were fabricated via air–water interfacial assembly and the dependence of supramolecular chirality on the assembly of the achiral double-decker molecules was identified. Interestingly, the corresponding supramolecular chirality in the solid-state can be reorganized with amplification of the Cotton effect and formation of helical nanostructures upon storage at room temperature and atmospheric pressure. These results open new perspectives for the regulation of supramolecular assemblies.
