Abstract

(Figure Presented) The coordinatively unsaturated sites in MIL-101, Cr 3(F,OH)(H2O)2O[(O2C)-C 6H4(CO2)]3·nH2O (n≈25), having zeotypic giant pores can be selectively functionalized in a way differing from that of mesoporous silica. Metal-organic frameworks, grafted with ethylenediamine or diethylenetriamine on the unsaturated CrIII sites of MIL-101, exhibit remarkably high activities in the Knoevenagel condensation relative to that of the mesophase.
