表征了一维可转化配位聚合物主体的乙醇蒸汽吸附行为和包裹体晶体结构。在相变或两相平衡过程中，由于“质量诱导相变”的性质，出现了吸附跳跃现象，并伴随着异常的吸附热焓。被包含的乙醇客体在通道内选择性地形成O-H...O氢键对，这表明在热力学因素的控制下，客体和通道表面之间的分子间协同作用在孔道中选择性地构建了特定的簇/聚集体。
The ethanol vapor adsorption behavior and the inclusion crystal structure of a 1D-transformable coordination polymer host were characterized. The adsorption jump was observed during phase transition or two-phase equilibrium with abnormal adsorption enthalpy caused by the nature of "mass induced phase transition." The included ethanol guests selectively form O-H...O hydrogen bonded pairs inside channels, suggesting selective construction of a specific cluster/aggregate in pores under control of thermodynamic factors and cooperative intermolecular interactions among the guest and channel surface.
