A simple quinoline derivative (quinoline-base sensor) was synthesized and investigated by its sensing properties towards various metal ions in CH3CN. Quinoline-base sensor showed a highly selective fluorescent enhancement towards Mg2+. The association constant of a 1:1 complex between quinoline-base sensor and Mg2+ was determined as 1.91×107M−1. The detection limit of quinoline-base sensor for the...
A new indole-based fluorescent chemosensor 1 was prepared and its metal ion sensing properties were investigated. It exhibits high sensitivity and selectivity toward Hg 2+ among a series of metal ions in H 2 O–EtOH (7:1, v/v). The association constant of the 1:1 complex formation for 1-Hg 2+ was calculated to be 9.57×10 3 M −1 , and the detection limit for Hg...
