Gate phenomena, which 7 different elastic layer-structured MOFs (ELMs) consisting of different building blocks show, were examined by measuring gas sorption isotherms at different temperatures. Conditions for the gate phenomenon of each ELM were understood. The double-step gate phenomenon of ELM-11 was examined by measuring gas sorption and X-ray diffraction. Almost the same CO2 sorption amount and interlayer expansion for the 2nd step were obtained for those at the 1st step. This suggested that ELM-11 should involve a double-step swelling reaction even for gaseous CO2 molecules. Sorption and desorption heats for the gate phenomenon of ELM-11 ([Cu(bpy)2(BF4)2) were measured. The stabilization of the structure of ELM-11 by CO2 incorporation into the crystal lattice was shown in the gate phenomenon from the energetic viewpoint. Another candidate reaction for a chemical heat pump using CO2 was also found for the CO2 occlusion reaction of Na2CO3 or K2CO3 under moist condition.

栅极现象通过在不同温度下测量气体吸附等温线来检查7种不同的弹性层结构的MOF（ELM）（ELMS）。了解每个榆树的栅极现象的条件。通过测量气体吸附和X射线衍射检查ELM-11的双步门现象。在第一步中，获得了第二步的几乎相同的二氧化碳吸附量和层间膨胀。这表明，即使对于气态二氧化碳分子，ELM-11也应涉及双步肿胀反应。测量了ELM-11（[CU（BPY）2（BF4）2）的栅极现象的吸附和解吸热。从能量视图中显示了在栅极现象中示出了通过二氧化碳掺入到晶格中ELM-11的结构的稳定。在潮湿的条件下，还发现了使用CO2的化学热泵的另一个候选反应，用于Na2co3或K2CO3的CO2闭塞反应。
