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.

门现象，其中7个不同的弹性层结构的MOFs（ELMs）组成的不同的积木显示，通过测量在不同温度下的气体吸附等温线进行了研究。了解了每个ELM出现门现象的条件。通过气体吸附和X射线衍射研究了ELM-11的双台阶门现象。第二步的CO2吸附量和层间膨胀量与第一步几乎相同。这表明，ELM-11应该涉及一个两步溶胀反应，即使是气态CO2分子。测定了ELM-11（[Cu（bpy）_2（BF_4）_2）的吸附热和脱附热。从能量的观点来看，通过将CO2掺入晶格中来稳定ELM-11的结构，这在门现象中示出。在潮湿条件下，Na_2CO_3或K_2CO_3的CO_2吸藏反应也被发现是利用CO_2的化学热泵的另一个候选反应。
