Stepwise synthesis via mechanochemical reaction for multistate redox-active 2D Zinc(ii) coordination network

Abstract

A multistate redox-active coordination network was prepared by stepwise synthesis via mechanochemical reaction to overcome the low solubility of ligands. Solid-state grinding between sparingly soluble ligands and metal ions lead to the formation of a soluble intermediate. A two-dimensional (2D) coordination network possessing open channels and iodinated pores was prepared by using the intermediate. The redox activity of the network, which was derived from ligands, was confirmed by electron spin resonance (ESR) spectroscopy and solid-state cyclic voltammetry. © 2018 The Chemical Society of Japan
