中文摘要：

以腺嘌呤和溴化铜（氯化铜）为原料,采用慢扩散合成法,合成多孔氢键金属-有机框架材料MPM-1-Br和MPM-1-Cl。采用SEM、PXRD、TGA及比表面积分析等技术对材料进行综合表征,并测定了此二种同构多孔氢键金属-有机框架材料对乙炔和二氧化碳单组分气体的吸附等温线。实验结果表明,MPM-1-Br和MPM-1-Cl的比表面积分别为373 m2·g-1和417 m2·g-1,且在〈240℃的温度范围内有良好的稳定性;在298 K和总压100 kPa下,通过IAST理论计算得到其对C2H2/CO2混合气体（体积比50：50）的吸附选择性分别达到了3.8和3.0,与HKUST-1（4.7）和UTSA-30（3.3）等金属-有机框架材料有相当的分离性能。

英文摘要：

Two porous hydrogen-bonded organometallic frameworks, termed as MPM-1-Br and MPM-1-Cl,were synthesized from adenine and CuBr2（or CuCl2） at room temperature by slow diffusion method. The synthesized materials were characterized by analysis techniques including SEM, PXRD, TGA and specific surface area analysis. Single-component adsorption isotherms for acetylene and carbon dioxide on these materials were also determined.The experimental results revealed that MPM-1-Br and MPM-1-Cl have moderately high BET surface（373 m2·g-1, 417 m2·g-1）, and they show good thermo stability at temperature up to 240℃. The calculations were performed using the ideal adsorbed solution theory（IAST） based on the single-component adsorption isotherms, obtaining the adsorption selectivity of MPM-1-Br and MPM-1-Cl for binary mixture of acetylene and carbon dioxide（50：50, volume ratio） to be 3.8 and 3.0 at temperature of 298 K and total pressure of 100 kPa, respectively, which are comparable to those on HKUST-1 and UTSA-30.
