Abstract
The synthesis of a novel bis-crown quinoxalino [2′, 3′: 9, 10] phenanthro [4, 5-abc] phenazine discotic and its binding properties to a series of alkali and alkaline-earth metals is reported. A schematic representation of the binding equilibrium of the sensor to the metal is proposed. The binding constant of the sensor to barium (II) was estimated to be 1.4× 104M− 1 based on 1H NMR studies.
