title: Encapsulation of small molecules by a cavitand porphyrin self-assembled via quadruple hydrogen bonds.
abstract: A new and stable quadruple hydrogen-bonded capsule, tetracarboxylcavitand.meso-tetra(2-pyridyl)porphyrin (1 x 2) has been synthesized and spectroscopically characterized. 1 x 2 can encapsulate small molecules of various size from methane to cyclopentane. The guest and host exchange rates were evaluated by EXSY.
