摘要
Zinc(II) coordination complexes, each having two linearly oriented peripheral carboxylate units, combine with 3,3'-dimethylbenzidene pillars to create channeled structures that host small organic guests. The porous solids reported here are connected solely via strong, charge-assisted hydrogen bonds and contain guests that vary in size, shape, and degree of hydrophobicity. The hydrogen-bonded framework is maintained upon guest loss, under vacuum and up to similar to 200 degrees C. The strength and flexibility of these frameworks make them ideal candidates for molecular storage, separations, guest exchange, and guest transport.
