Abstract
Krunski eteri spadaju u skupinu spojeva koji se zovu makrociklički spojevi. Karakterizira ih prstenasta struktura koja se sastoji od niza eterskih jedinica između kojih se mogu nalaziti i heteroatomi poput dušika, sumpora, itd. Najviše su proučavani zbog sposobnosti stvaranja kompleksnih spojeva s raznim ionima metala. U takvom kompleksnom spoju ion metala je „gost“ a krunski eter je „domaćin“. Krunski eter određene veličine prstena favorizira kompleksiranje određenog iona metala. Ta pojava se naziva „templatnim efektom“ te zahvaljujući njemu je moguće unaprijed odrediti strukturu kompleksnog spoja koja će savršeno odgovarati veličini metalnog iona. Primjer takvog domaćina su sferandi, koji su visokoselektivni prema ionima kalija te se zbog toga koriste u određivanju koncentracije kalija u krvi bolesnika. Budući da mogu kompleksirati i anione metala- alkalide, kriptandi su primjenu našli u ionskoj kromatografiji i anionskoj polimerizaciji.
Abstract (english)
Crown ethers are a class of compounds that are called macrocycles. They have ring structure that consists of ether units which can alternate with heteroatoms such as nitrogen, sulphur, etc. The most studied property of crown ethers is their ability to complex various ions. In such compound metal ion is guest and crown ether is host. Crown ether of different ring size favor complexation with different metal ion. This concept is called „template effect“ so one can design crown structure that will perfectly fit with metal ion. Example of this type of host are spherands that are highly selective toward potassium ions so they are turned into sensors for detection of K+ concentration in blood serum. Because of their ability to complex metal anions- alkalides cryptands are used in ion chromatography and anionic polymerization.
