Influence of crystallization solvents on the crystal structures and supramolecular assemblies of [2]naphthyl-extended pillar[6]arene

Abstract

Newly synthesized [2]naphthyl-extended pillar [6]arene was crystallized from a range of solvent systems to examine the influence of crystallization conditions on its structural and supramolecular behavior. Single-crystal X-ray diffraction revealed solvent-dependent packing modes, giving rise to distinct assemblies including inclusion complexes, and supramolecular polymer driven by solvent guest molecules. The variations are governed by a solvent-host interactions, emphasizing the crucial role of solvents in directing supramolecular assembly in the solid state. The resulting supramolecular assemblies were fully characterized using single-crystal X-ray diffraction and Hirshfeld surface analysis.
