Selective Generation of Organic Aggregates Included within Metal−Organic Micropores through Vapor Adsorption

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.
