(Self) assembled news: recent highlights from the supramolecular chemistry literature (Quarter 1, 2023)
The synthesis of pillar[n]arene macrocycles has been one of the most influential developments in the recent history of supramolecular chemistry. These macrocycles have a rich host – guest chemistry and can often be prepared in a single step. Writing in Nature Synthesis, a team led by Andrew Sue (winner of the 2021 Sessler Early Career Research Prize) have shown that pillar[5] arene derivatives can be used to form well-defined chiral nanotubes [1]. The nanotubes are formed in a singlestep condensation reaction of a penta-formyl macrocycle and phenylenediamine in quantitative yield (Figure 1). The penta-formyl compound was previously reported by the same group and was synthesised from tiara[5]arene, which was itself prepared from a rimdifferentiated pillar[5]arene [2]. Pillar[5]arenes are chiral but racemise rapidly in solution through rotation of the rings; however, in the nanotubes this rotation is locked and a pair of enantiomeric tubes were formed that could be separated using chiral HPLC. While the binding of chiral guests was not investigated, the nanotubes show strong binding of dihydroxyalkanes and dibromoalkanes with selectivity based on guest size.
期刊介绍:
Supramolecular Chemistry welcomes manuscripts from the fields and sub-disciplines related to supramolecular chemistry and non-covalent interactions. From host-guest chemistry, self-assembly and systems chemistry, through materials chemistry and biochemical systems, we interpret supramolecular chemistry in the broadest possible sense. Interdisciplinary manuscripts are particularly encouraged. Manuscript types include: high priority communications; full papers; reviews, and; Methods papers, techniques tutorials highlighting procedures and technologies that are important to the field. We aim to publish papers in a timely fashion and as soon as a paper has been accepted and typeset it will be published in electronic form on the Latest articles section of the website. The two most important review criteria are that the paper presents high-quality work that fits generally into the broad spectrum of activities in the supramolecular chemistry field. Under normal circumstances, Supramolecular Chemistry does not consider manuscripts that would be more suitable in a highly specialized journal. This includes, but is not limited to, those based mostly or exclusively on topics such as solid state/X-ray structures, computational chemistry, or electrochemistry. .
