A new highly selective calix[4] arene-based fluorescent probe for Ca2+
A new calix[4]arene Schiff Base with two anthracenes has been synthesized; Investigation of its photo-physical and complexing properties towards alkali and alkaline earth metal ions reveals a high selectivity for Ca2+ in MeCN-ethanol mixtures.
