7 Supramolecular Chemistry

The selective complexation of cationic species was the earliest goal of supramolecular chemistry and continues to attract effort and interest. Over the last five years, Gunnlaugsson and co-workers at Trinity College Dublin have produced a wide variety of colorimetric sensors for ions, nucleic acids and oligonucleotides. In 2004, this group reported the synthesis of a colorimetric sensor for Cu(...

Organic chemistry in water.

Water has emerged as a versatile solvent for organic chemistry in recent years. Water as a solvent is not only inexpensive and environmentally benign, but also gives completely new reactivity. The types of organic reactions in water are broad including pericyclic reactions, reactions of carbanion equivalent, reactions of carbocation equivalent, reactions of radicals and carbenes, transition-met...

Chemistry in nanoconfined water.

Nanoconfined liquids have extremely different properties from the bulk, which profoundly affects chemical reactions taking place in nanosolvation. Here, we present extensive ab initio simulations of a vast set of chemical reactions within a water lamella that is nanoconfined by mineral surfaces, which might be relevant to prebiotic peptide formation in aqueous environments. Our results disclose...

Radiation chemistry: Radical water.

I onizing radiation is known to be harmful to living organisms because it creates reactive radicals and charged species. In particular, highly energetic X-rays that ionize by removing one of the innermost (core) electrons of an atom lead to a cascade of events that must be better characterized if we are to fully understand their toxic effects 1. Writing in Nature Chemistry, Petr Slavíček, Bernd...
