Framework: Vs. side-chain amphidynamic behaviour in oligo-(ethylene oxide) functionalised covalent-organic frameworks

We present a family of covalent organic frameworks that have been functionalized with oligo-(ethylene oxide) chains of varying lengths. Because of the open structure of the COFs, the side chains do not interfere with their crystallization obtaining materials with predictable crystal structure. The difference in length of the side-chains allowed for the determination of amphidynamic behaviour with the use of 13C solid-state NMR relaxation methods. Computational calculations further contribute to understanding the atomistic dynamic behaviour of the different atoms. This study demonstrates the ability to design complex behaviour in organic crystals.

Resorcin[4]arene-based molecular baskets and water-soluble container molecules: Synthesis and 1H NMR Host-guest complexation studies

Resorcin[4]arene-based molecular baskets, with four free or methylene-bridged HO groups, and water-soluble container molecules bearing poly(ethylene glycol) chains of different lengths on the lower rim and cap have been synthesized. These cavitands, toppe
