Posted by A thematic issue of Beilstein Journal of Organic Chemistry entitled
‘Novel macrocycles – and old ones doing new tricks’
has been recently published. The editors of the issue were Prof. Wei Jiang, Southern University of Science and Technology, Shenzhen and Prof. Christoph A. Schalley, Freie Universität Berlin. The editors write in the preface of the issue: ‘Nowadays, the use of macrocycles has significantly diversified. They are not only tools for studying molecular recognition and molecular machines, but are also key components for sensing, supramolecular catalysis, (chiral) separation, drug delivery, or smart materials. Many new macrocycles have recently been reported, with pillararenes being one of the most prominent examples. These new macrocycles often possess new properties. In addition, the old ones have also been taught new tricks. Together, this enormously expands the abilities and the utility of macrocycles; they “boldly go, where no one has gone before”, exploring a true supramolecular universe’.
Among the various peculiar macrocycles some studies on cyclodextrins are also found:
