| dc.description.abstract | The constant search for new and unusual hosts is what pushing supramolecular chemistry forwards. The scope of their applications is immense: drug recognition and reversal, novel materials, catalysis, purification and separation of chemicals etc., not to mention a fundamental insight into chemical and biological systems that can be gained by studying them. Sulfonated calixarenes constitute an important family of such hosts. Their exceptional binding properties coupled with water-solubility, high stability and endless potential for synthetic modifications make them perfect candidates for study. There are numerous examples of those macrocycles, modified in a way that introduces a fluorescent chromophore, enabling them to be used as detectors for various guests. Yet, cases of them being able to change their properties upon irradiation with light – having a photoswitchable chromophore – remain particularly scarce. This work attempts to present such system – a pair of sulfonated calixarenes, calix[4] and calix[5]arene with a hemiindigo moieties installed on the upper rim. Here we demonstrate their synthesis, as well as a study into their photophysical and supramolecular properties. Various advanced NMR techniques such as DOSY and NOESY were used in conjunction to demonstrate differences in their aggregation. | |
