Abstract

Exceptionallyflexible inclusion compound having three-dimensional(3D) solvent-accessible voids was built from single 1,3-ethylene diamidebridged p-tert-butyl-calix[4]arene. The robustnessof the crystalline order originates from a fascinating square-gridframework of open molecular capsules that is built entirely from vander Waals forces and weak hydrogen bonding. Yet, its flexibility isinduced by a controlled solvent-directed “breathing behavior”.The 3D network of channels generates extrinsic voids sufficientlyelastic to trap different sizes of alcohol molecules. Careful extractionof solvent from these voids produces 3D nanoporous molecular crystalswith controlled pore size. [ABSTRACT FROM AUTHOR]
