title: Extended covalent containers: synthesis and guest encapsulation.
abstract: The synthesis and characterization of two new covalent capsules are described. The structures use biphenyl and azobenzene spacers capped on both ends with deep cavitands. The tubular capsules are robust in a range of media and accommodate guests as long as squalene.
