: In this study, we articulate the synthesis of camphorsulphonic acid doped conducting polyaniline (CSA-PANi) for the detection of typical nitroaromatic (NAC) (picric acid, PA). The synthesised CSA-PANi is characterised by its structure and thermal behaviour. The detection of PA is studied through the observed intense quenching of fluorescence signals in the emission spectra of the CSA-PANi solution. The detection limit employing S-V equation is found to be 5ppm in a 5ppm solution of CSA-PANi solution. The mechanism of quenching through the formation of exciplex complex formation is reported in the present study.
