dc.description.abstract | © 2019 The Royal Society of Chemistry and the Centre National de la Recherche Scientifique. Monosubstituted pillar[5]arenes containing a phosphonate fragment were successfully obtained in good yields. It was found that the introduction of bulky fragments containing tetra-coordinated pentavalent phosphorus atoms prevents self-Assembly of monosubstituted pillar[5]arenes and the formation of supramolecular polymers. Pillar[5]arenes with phosphonate and 1-Aminophosphonate substituents demonstrated recognition towards Na+, K+, Cs+ and Pb2+. Their ability to form complexes with these cations was evaluated by UV spectroscopy. Dynamic light scattering (DLS) revealed the formation of aggregates with K+, Cs+ and Pb2+. It was established that the substituent at the α-carbon atom of the aminophosphonate fragment played a significant role in Pb2+ binding. DLS and transmission electron microscopy revealed that Pb2+-induced aggregation formed particles with a monodisperse distribution of 0.02-0.23 and a hydrodynamic diameter of 58-178 nm. | |
