A highly stable and hierarchical tetrathiafulvalene-based metal organic framework with improved performance as a solid catalyst

Abstract

[EN] Herein we report the synthesis of a tetrathiafulvalene (TTF)-based MOF, namely MUV-2, which shows a non-interpenetrated hierarchical crystal structure with mesoporous one-dimensional channels of ca. 3 nm and orthogonal microporous channels of ca. 1 nm. This highly stable MOF (aqueous solution with pH values ranging from 2 to 11 and different organic solvents), which possesses the well-known [Fe3(¿3-O)(COO)6] secondary building unit, has proven to be an efficient catalyst for the aerobic oxidation of dibenzothiophenes. ; The work has been supported by the European Union (ERC-2016-CoG 724681-S-CAGE) and the Spanish MINECO (CTQ 2014-59209-P, CTQ2017-89528-P and MAT2015-71842-P). We also thank the Spanish government for the provision of a Severo Ochoa project (SEV-2016-0683) and a Maria de Maeztu project (MDM-2015-0538). G.M.E. and M.S. thank MINECO for a Ramon y Cajal and a Juan de la Cierva-Formacion fellowships, respectively. We thank J. M. Martinez-Agudo, G. Agusti and J. Romero from the University of Valencia for their magnetic and cyclic voltammetry measurements. We thank the Diamond Light Source (UK) for the synchrotron beamtime.
