P=O functional group-containing cryptands: from supramolecular complexes to poly[2]pseudorotaxanes

Chem Commun (Camb). 2015 Feb 14;51(13):2667-70. doi: 10.1039/c4cc09487e.

Abstract

Two types of cryptand-based host-guest complexes were constructed successfully, in which P=O functional groups were located at the different positions of the third arms. Consequently, supramolecular poly[2]pseudorotaxanes with almost linear and zigzag shapes were formed in the solid state.
