Synthesis and binding investigations of novel crown-ether derivatives of phenanthro[4,5- abc ]phenazine and quinoxalino[2′,3′:9,10] phenanthro[4,5- abc ]phenazine

Abstract

The synthesis and binding investigation of novel crown-ether derivatives of phenanthro[4,5-abc]phenazine and quinoxalino[2′,3′:9,10] phenanthro[4,5-abc]phenazine sensors are reported. The binding studies of these sensors with an array of alkali and alkaline-earth metals are exploited using UV-vis, fluorescence and nuclear magnetic resonance spectroscopies. © 2013 © 2013 Taylor & Francis.
