18-Corona-6

Descrizione:

18-Corona-6, con il numero CAS 17455-13-9, è un poliètere ciclico appartenente alla famiglia degli eteri a corona. La sua struttura molecolare consiste in un anello di sei gruppi eterei, che crea una cavità capace di legare selettivamente cationi, in particolare metalli alcalini come sodio e potassio. Questa selettività deriva dalle dimensioni della cavità, che è ben adatta ad accogliere questi ioni. 18-Corona-6 è tipicamente un solido cristallino incolore, solubile in solventi organici polari come acetone e metanolo, ma insolubile in acqua. Mostra forti proprietà di complessazione, rendendolo prezioso in varie applicazioni, inclusi elettrodi selettivi per ioni, processi di estrazione e come catalizzatore di trasferimento di fase nella sintesi organica. Inoltre, la sua capacità di formare complessi stabili con ioni metallici ha implicazioni nella chimica analitica e nella scienza dei materiali. Le proprietà uniche del composto derivano dalla sua struttura molecolare, che consente una coordinazione e stabilizzazione efficace degli ioni, rendendolo un composto significativo nella chimica supramolecolare.

CAS: 17455-13-9

18-Crown-6-ether (18C6; 1,4,7,10,13,16-Hexaoxacyclooctadecane) is an organic compound utilized in forming stable microcapsule responsive layers, which can be further assembled into bilayer microcapsules. For instance, a responsive layer can be prepared using 18-Crown-6-ether and coated with a K+ stabilized G-quadruplex crosslinked hydrogel layer. In the presence of Mg2+ ions, 18-Crown-6-ether and K+ ions can respectively dissociate and lock with the G-quadruplex crosslinked layer, achieving switchable controlled release of the payload.
