• ions and molecules by designed synthetic receptors is currently of major interest in the area of molecular recognition [1][2][3]. Among various sensing techniques available for clinical, biological and environmental analyses, fluorescence sensing is unique because of high sensitivity and compatibility

• - and dicarboxylic acids by a large number of receptors of different architectures is known [11][12][13][14]. We have also reported a series of synthetic receptors for carboxylic acids of various types [15][16][17][18]. In continuation, we report here a new quinoline based sensor 1 (Figure 1) which is
