报告摘要

Owing to their large internal surface area, their porosity and synthetic tunability, metal-organic frameworks (MOFs) have become appealing research targets for a variety of applications, including energy storage, catalysis, and as (opto)electronics components. Amongst MOFs that are electrically conducting, those that propagate charge transport by a diffusional electron hopping mechanism are a rich research field, both from a fundamental as well as applied viewpoint.

In this contribution, we will discuss a variety of MOFs that contain electronically isolated, redox active linkers, and determine factors that govern charge transport, in particular, the coupling between electron and cation transport.We will show that electric conductivity through redox conducting MOFs is strongly dependent on the redox composition of the MOF, and can be tuned by up to four orders of magnitude.Applications of redox conducting MOFs within molecular catalysis of electrochemical reactions,electrochromic materials or as electronics component will be demonstrated.

报告人简介

Sascha Ott studied in Germany and Australia, and obtained his PhD in Chemistry at University College London, U.K., in 2002. Following postdoctoral work with Prof. Licheng Sun at Stockholm University, Sweden, he moved to Uppsala University in 2004, and became Professor in Synthetic Molecular Chemistry at the Department of Chemistry – Ångström in 2017. He received a Consolidator Grant from the European Research Council (2015), a highly prestigious project grant from the Knut & Alice Wallenberg Foundation (2019), and was awarded the Thuréus Prize from the Royal Society of Sciences Uppsala (2017). He has published 175 peer-reviewed articles (ca. 9700 citations; h-index 54), and is chair-elect of the Gordon Research Conference on Solar Fuels (2028). Research in the group is centered around different topics at the interface of organic chemistry and molecular inorganic chemistry. These include works on the development of molecular redox catalysts of energy relevance, more recently in the confinements of metal-organic frameworks (MOFs). Over the last five years, redox-conducting MOFs have been the center of focus in the group.
