“…Calixarenes and their thia-analogs are macrocyclic ligands that offer broad opportunities of specific accumulation and complexation of various organic and inorganic species due to multi-point interactions with macrocyclic moiety and substituents bearing various functional groups [21,22]. Due to flexibility of the structure and variety of functional groups involved in the substituents of upper and lower rim, calixarenes provide a promising platform for the synthesis of specific receptors towards pesticides and their nonspecific accumulation via hydrophobic interactions.…”

New acetylcholinesterase biosensors have been developed on the base of screen-printed electrodes modified with Co-phtalocyanine and polycarboxylated thiacalixarenes as enzyme support. The biosensors showed improved operational and analytical characteristics and high accuracy of the signal measurement. The biosensors developed made it possible to detect 3-200 ppb of paraoxon and 1-50 ppb of malaoxon with detection limits down to 2 and 0.05 ppb, respectively (incubation time: 15 min). The influence of macrocyclic receptors was related to nonenzymatic accumulation of the analytes within the surface layer and electrostatic interactions with remaining free carboxylic groups of the support. The reliability of the inhibition measurements was confirmed by testing spiked samples of sparkling and tape waters. were determined in 15 min incubation step with very low matrix effect in spiked tap and mineral water. -The steric limitations and specific interactions with the substrate and inhibitors specify the positive effect of macrocycles and their structure influence on the biosensor characteristics.

This research was focused on synthesizing 3 zirconium complexes with phenol ligand and preparing ZrO2 from synthesized complex through the method of thermal decomposition was the result of the work. Nanoparticles of ZrO2 were synthesized after the complexes were decomposed in autoclaves at varies temperatures according to the different ligands.FT-IR spectroscopy, UV-Vis spectroscopy, chemical analyzing and metal analyzing were used for investigating the complex as analyzing methods.Furthermore, for the obtained nanoparticle, XRD, UV–Vis, FESEM and EDAX analyses were chosen for analyzing. Based on the result, synthesized ZrO2 are able to remove harmful organic compounds under UV light.

“…However, the synthesis of the artificial sites that could provide high binding affinity, selectivity and sensitivity to keep analyzing substance and maintain stability over time analysis so far is a big issue for the scientific community. Construction of such types of sites is an important task for modern biosensorics [1,2]. Among the objects of the supramolecular chemistry research the special place belongs to calixarenas [2,3] which are a class of macrocyclic compounds formed by the condensation of phenol typically para-substituted with formaldehyde.…”

H 23 were selected by the computer modeling for the investigation of their absorption properties in respect of such mycotoxins as patulin, T2, aflatoxin B1 and zearelenon. It was found that all used calix[4]rezortsynarenes interact with the mentioned mycotoxins but the structure type R(H)-C 11 H 23 was characterized by the highest level of sorption activity. Based on the level of the concentration of the testedmycotoxins and on the determined association coefficient in the reaction of certain mycotoxins iththecalix[4]rezortsynarenes it should be considered that the level of specificity or too low, or nonexistent. Application of the calix[4]rezortsynarenes as selective sites can be recommended only for general screening the presence of mycotoxins in the environment.
