摘要：
A rare three-dimensional (3D) microporous lanthanide metal-organic framework, {[Yb(BTB)(H2O)](MeOH)(2)(H2O)(n) (1), with 1D nano-sized channels has been constructed by bridging helical chain secondary building units with 1,3,5-Benzenetrisbenzoic acid (H3BTB) ligand. The highly rigid and stable framework contains a 1D triangular channel-type structure with highly polar pore surfaces decorated with abundant open metal sites. The desolvated framework {[Yb(BTB)]}(n) is found to exhibit permanent porosity with high CO2 storage capacities and significant selective sorption of CO2 over CH4 around room temperature.
