摘要：

A phenanthroline-functionalized Cd-II aminoterephthalate [Cd(NH2-bdc)(phen)](n) (NH2-bdc=2-aminobenzenedicarboxylic acid, phen=1,10-phenanthroline) metal-organic framework (MOF) displays CO2-selective adsorption properties and photoluminescence induced by phenolic guests. The inherently guest-free, rigid amine-rich framework exhibits substantial CO2-selective adsorption at ambient temperatures (both at 273 and 298 K) over other flue gases like N-2, CH4, O-2, Ar and H-2, with a high isosteric heat of adsorption at zero coverage (Delta H-ads approximate to 34 KJmol(-1)). Moreover, the fluorescent phenanthroline guest introduced to the MOF results in an excellent photoluminescence signature, which can serve as a marker for tuning phenolic-guest-induced luminescence. This marks the first report of observing distinct fluorescence responses to differentially functionalized phenolic analytes, in the domain of coordination polymer materials.
