Host-guest charge transfer for scalable single crystal epitaxy of a metal-organic framework

A. Mantel, B. Stöger, et al.

This exciting research showcases the advancements in single crystal homoepitaxy of a metal-organic framework featuring zinc and terephthalate ions. The study reveals the remarkable growth of centimeter-scale crystals due to unique electrostatic attractions, paving the way for scalable bulk MOF production, developed by Arthur Mantel, Berthold Stöger, Alexander Prado-Roller, and Hidetsugu Shiozawa.

Abstract
This study demonstrates single crystal homoepitaxy of a metal-organic framework (MOF) built of zinc, acetate, and terephthalate ions, encapsulating octahedral zinc dimethyl sulfoxide (DMSO) complex cations within its 1D channels. The charge-transfer MOF grows stepwise to centimeter-scale square cuboids due to host-guest electrostatic attraction. This scalable epitaxy, with no apparent size limits, is attributed to the ionic nature of the anionic framework and cationic 1D molecular fillers, opening avenues for bulk MOF crystal growth.
