Abstract
Diaza-18-crown-6 appended with two 5-chloro-8-hydroxyquinoline groups can serve as an effective chemosensor for Mg2+. The modified macrocycl e will fluoresce in the presence of Mg2+ but not with other alkaline e arth ions at pH 7.2. Mg2+ concentrations can be measured in the presen ce of Na2+, K+, Ca2+, Sr2+ and Ba2+. (C) 1998 Elsevier Science Ltd. Al l rights reserved.
