Resumo(s)
Chemical sensors have been playing a crucial role in analytical chemistry, bio-medicinal science and environmental chemistry.
Chemosensors offer na accurate and low-cost finding of anions, cations, enzymes and toxic metal ions with high selectivity and sensitivity. In this regard, many organic compounds have been synthesized and are being used as successful chemosensors, however calixarenes offer distinct advantage in term of selectivity and the easy incorporation of a fluorophore into the structure.
Cation complexing ligands containing calix[4]arene have been used to obtain more selective metal ions receptors.
Herein, we report fluorescente calix[4]arene-based sensors with diferente molecular architecture [3] and their potentialities to address the detection of toxic metals. Using fluorescence as the signal transduction technique, experiments have shown that CALIX-OCP-2-CBZs are the most sensitiveto Cu.
