摘要

•Two pyrenyl-pyridyl-acrylonitrile compounds as ClO−/HSO3− probes were developed.•The probes can discriminably detect ClO−/HSO3− with blue fluorescence enhancement.•Neutral probe 1 is resolved into strong fluorescence 1-pyrene-carboxaldehyde by ClO−.•HSO3− is added to CC bridge of methylate probe 2 by nucleophilic addition.
