In this study, we prepared an efficient chemosensor based on 2,3-diaminophenazine hydrochloride, and it exhibited good dissolvability in water; more importantly, it could act as an efficient chemodosimeter for the selective detection of CN- in pure water. Upon reacting with CN-, 2,3-diaminophenazine hydrochloride (Q1) displayed a remarkable visible and fluorescence response simultaneously with significant changes in both absorption and fluorescence spectra. Furthermore, the absorption and fluorescence detection limits of CN- were 1.95 x 10(-7) M and 1.13 x 10(-9) M, respectively. For practical applications, test strips based on this chemosensor could serve as convenient CN- detection tools. The chemosensor was also successfully applied to the detection of CN- in plant seeds and several natural water samples.
