Abstract:
Two chelating-amino-functionalized lanthanide metal-organic frameworks, Er-DADQ and Eu-DADQ, were synthesized with a flexible dicarboxylate ligand based on quinoxaline (H2DADQ = N,N'-dibenzoic acid-2,3-diaminoquinoxaline). N2 adsorption indicates that they exhibit a stable microporous framework with a BET surface area of 136.78 m(2) g(-1). CO2 adsorptions have also been studied at different temperatures. The amino groups in the MOFs enhanced the uptake of RhB with COOH groups. RhB-MO and RhB-CV separations have also been successfully conducted. The MOFs act as efficient Lewis acid catalysts for the cyanosilylation of aldehydes and ketones in high yields in a short reaction time due to the higher Lewis acidity and open sites of the metal ions after activation.

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
