Hot Article: Versatility in building supramolecular materials

In this CrystEngComm Hot Article, which is part of a themed issue celebrating the achievements of the late Professor Fumio Toda entitled “Reactions in Molecular Solids and Host-Guest Systems“, Anthony Coleman and Oksana Danylyuk et al. report their results on a systematic investigation of the solid-state complexes of para-sulphonato calix[4]arene (C4S) with 1,10-phenanthroline (Phen).  The team prepared four supramolecular complexes of C4S with Phen in single-crystal form and their structures determined by X-ray diffraction.

Cyclodextrins, crown ethers, cryptands and calix[n]arenes are the most important categories of supramolecular hosts. Acid derivatives such as para-sulphonato-, O-phosphonato- or O-alkylcarboxylato-calix[n]arenes present the advantage of being hydrosoluble and thus apt for study with regard to their biological properties and their complexation abilities towards molecules of biological interest.
