Abstract
The review consists of two parts. In the first part applications of calixarenes as sensors are described, paying attention to sensors of metal ions. The second part is concerned with other special applications of calixarenes.
Highlights
Calixarenes are interesting cage macrocycles, widely investigated due to their valuable properties, especially formation of inclusion complexes;[1] these macrocycles are promising for a variety of applications.[2]
The method is suitable for routine analysis, it combines the separation on AQUALIX with fast ICP-MS measurement
First the usual step of spontaneous deposition of polonium on silver disc is performed for separation of polonium, the uranium extraction on AQUALIX column occurs, followed by alpha spectrometry counting. (Scheme 2)
Summary
Calixarenes are interesting cage macrocycles, widely investigated due to their valuable properties, especially formation of inclusion complexes;[1] these macrocycles are promising for a variety of applications.[2]. The present paper is a continuation of our previous reviews concerning covalently and noncovalently bound calixarene assemblies,[17] calixarenes functionalized at wide and narrow rims,[18] calixarenes substituted at meso positions,[19] calixarene complexes with metal ions,[20] as well as calixarenes and resorcinarenes.[21]. Calixarenes containing modified meso bridges are known,[22] they are calixradialenes,[23] ketocalixarenes[24] and homocalixarenes.[25,26] The noncovalent calixarene assemblies with porphyrins[27,28,29] are recently the theme of a large amount of reports.[30]
