Abstract

Abstract: Ln 3+ ‐bearing Metal‐Organic Frameworks (MOFs) are attracting much attention because of their unique luminescence properties and the possibility of fine‐tuning the metal coordination spheres by post‐synthetic modification (PSM). Here, we report PSM of the well‐known IRMOF‐3 by reaction with methyl 3‐chloro‐3‐oxopropanoate and pyridine‐2, 6‐dicarbonyl dichloride affording, respectively, IRMOF‐3‐CM and IRMOF‐3‐PY. 1 H NMR of the digested modified samples showed ca. 100 % conversion of the amino group. The pendant groups of PSM IRMOF‐3 were subsequently used to coordinate Eu +3 and Tb 3+ and the luminescence properties of the materials studied. Abstract : The well‐known Metal Organic Framework IRMOF‐3 was post‐synthetically modified with a facile synthesis method giving high yield of amino group conversion. The modified materials were subsequently used to coordinate lanthanide optical centres in their nanochannels. Beside a comprehensive structural characterisation of the new materials, the luminescence propertiesof the materials were studied
