Abstract Redox-active metal-organic frameworks (MOFs) have already demonstrated their unique advantages ORG GOJI BERRIES in the field of electrochromism over the past decade.However, controlling and modulating the electrochromic behaviors in specific MOFs remains a significant challenge, as most of the cases reported so far are achieved by designing and constructing new MOFs.Herein, we design a redox-active Zr-MOF with coordination unsaturated pockets, termed NKM-908, based on a naphthalene diimide containing tetratopic carboxylate ligand.The fabricated NKM-908 thin film exhibits a reversible electrochromic behavior, showing a color change from basically colorless to light yellow and then to green.Remarkably, two forms of distinct and precise modulations to the electrochromic performance of NKM-908 are achieved through installations of linear auxiliary bitopic carboxylate linkers (TPDC-X) into the coordination unsaturated pockets, i.
e.deepening the color and deriving new colors/shifting modes.This work is a successful attempt in tailoring the color change of electrochromic MOFs as required without synthesizing them from scratch.Considering the high efficiency and conveniency of this post-synthetic modification, such strategy opens up a versatile route in designing electrochromic materials, as well as facilely copyright Rangehood Vent Adaptor Kit extending their potential towards practical applications.
