DOI: 10.1016/j.microc.2019.104461
Abstract: ABSTRACT The colorimetric-fluorescent sensor ASHTI, synthesized by simple method, could sensitively and selectively sense bisulfite (HSO3−) in phosphate-buffered saline solution (pH 7.4) via the Michael-addition mechanism. ASHTI with D -π-A structure emitted red fluorescence, which… read more here.
