Sažetak
Calixarenes, which are among the most widely used host molecules in supramolecular chemistry, are macrocyclic oligomers consisting of phenolic residues linked by methylene bridges in the ortho position. [1] Many calixarene derivatives are known to be very efficient and selective receptors of ions and neutral molecules, [2] so it is not surprising that over the past decades they found application in biosensing, bioimaging, theranostics, and drug/gene-delivery. [3] Nevertheless, more multidisciplinary explorations of their physico-chemical properties and biomedical functions are needed to pave the path towards their potential clinical use. Here we present a thermodynamic study of the binding of three selected dyes (rhodamine B, auramine O, and fluorescein) by phenanthridine- based calix[4]arene derivatives 1 – 3. Unlike calixarene derivatives used for bioimaging previously, ligands 1 – 3 comprise aromatic phenantridine subunits which are expected to contribute to stabilization of their complexes with the dyes. All three ligands were shown to be good receptors for the selected dyes, making them very interesting candidates for biomedical applications.
