Significant centre metallic effects on the sensing properties of two isostructural lanthanide metal-organic frameworks

摘要

Two isostructural Ln-MOFs, [H2N(CH3)(2)][Ln(cppa)(2)(H2O)(2)] (Ln = Tb/Eu CTGU-1Tb/-1Eu, H(2)cppa = 5-(4carboxyphenyl)picolinic acid), were selected to investigate the effects of the different metal centre on the sensing properties. CTGU-1Eu can detect small organic molecule acetone and nitroaromatic explosives in water, whereas CTGU-1Tb can only detect explosive nitrophenol in water. (C) 2017 Elsevier B.V. All rights reserved.
