Abstract

Synthetic viability of calix[4]arene, surround by four functionalized sites, makes this an excellent pre-organized matrix for the elaboration of a ligand tetra functionalized. In view of this, there are many manuscripts grew up in creativity unifying strategic functions (in a framework macrociclo, semi-rigid) with the cavity formed. This architecture became particularly interesting in designing materials for catalysts supramolecular architectures and molecular probes based on transition metals. In this project modified quinolines by electron donors and/or acceptors groups attached to calixarene, aim to more efficient light-emitting materials, with potential application in devices e.g. OLEDs. The connection of 5,6-hydroxy-1,10-phenanthroline to calixarene, via an alkyl bridge, increases the cavity of the matrix and its selectivity to the specific cations, providing an appropriate arrangement for detection and subsequent study of disturb using electrochemical, spectroscopic and luminescent measures of this chemical system. The study of the properties of these systems toward cationic groups enable them as molecular sensors such as probes in bioassays and in the monitoring of localized interference caused by detection of cations, important for the development of ionophores and extractor agents.
