Colorimetric chemosensors are now considered as one of the most effective analytical method used in the environment monitoring. Colorimetric chemosensors for pH sensing can easily detect the primary danger or change of the surrounding environment pollution and source of infection and can prevent danger in the various fields. Quinaldine and Indole based colorants having the function of colorimetric chemosensors were synthesized. Synthesized colorants were characterized by 1H NMR, GC-Mass, EA and UV-Vis spectroscopy. Especially UV-Vis spectroscopy revealed that the color of each colorant solution was changed in basic conditions while no changes were observed in acidic condition. And then synthesized colorants were mixed with poly-acrylonitrile for electrospinning. Electrospun fibers containing each colorant were used as pH textile sensors and they were analyzed by SEM, XPS, and Spectrophotometer.
