title: Hydrogen bonded calixarene capsules kinetically stable in DMSO.
abstract: Half-life times up to 4 days in DMSO at room temperature are observed for the decomposition of dimeric capsules of urea substituted calix[4]arenes held together by a combination of hydrogen bonds, mechanical entanglement and cation-pi interactions.
