Abstract

Crystalline porous materials have received extensive attention due to their fascinating structures and wide applications. Herein, we reported a novel diphase 2D halogen-bonded organic framework (XOF-TPP) based on the 1,3,6,8-tetra(pyridine-4-yl)pyrene (TPP). XOF-TPP was constructed by the [N···I+···N] interaction between the pyridyl group of TPP and iodonium cation. The formation of XOF-TPP was monitored by X-ray photoelectron spectroscopy (XPS), IR spectroscopy, powder X-ray diffraction (PXRD), theoretical simulation, SEM, and HRTEM. Small-angle X-ray scattering (SAXS) indicated that the XOF-TPP exists in a 2D periodic structure solution. This diphase 2D halogen-bonded organic framework may hold promise for practical applications in supramolecular functional materials.
