  Abstract

This paper describes the synthesis and water sensing properties of a fluorescent photoinduced electron transfer (PET) sensor (5) with an extended operating sensing range. The 1,8-naphthalimide derivative (5) attached with a piperazine group and a carboxylic group was synthesized and applied as a fluorescent water sensor in watermiscible organic solvents. The fluorescence intensity of the dye 5 increased with increasing water content up to 80% (v/v) and the fluorescence intensities were enhanced 45-, 67- and 122-fold in aqueous EtOH, DMF and DMSO solutions, respectively. In aqueous acetone solution, the enhancement of the fluorescence intensities was somewhat lower (30-fold) but the response range was wider (0-90%, v/v).
