An unusual bifunctional Tb-MOF for highly sensitive sensing of Ba2+ ions and with remarkable selectivities for CO2–N2 and CO2–CH4†
Abstract
An unusual bifunctional Tb-MOF (TbL) was synthesized by solvothermal method. Luminescent measurements show that the TbL compound exhibits high sensitivity for Ba2+ ions in DMF solution. Moreover, TbL presents significant selective capture of CO2 from the mixtures of CO2–N2 and CO2–CH4, based on the studies of gas sorption capability. To the best of our knowledge, it is the first reported Tb-MOF with such highly sensitive luminescence response for Ba2+ ions and excellent selectivities for CO2–N2 and CO2–CH4.
