Recently, fluorescent labeling techniques have been greatly developed with the aid of highly optimized small-molecule fluorescent dyes, fluorescent proteins and advanced tagging techniques. Many reasonable strategies have been used to design fluorescent diarylethene, mainly focusing on the introduction of luminophores by conjugated junction and the modification of aryl cores in the diarylethene. Compared to thiophene, furan has superior properties such as solubility, biodegradable ability and rigidity fluorescence. Therefore, difurylethene is a better candidate for fluorescent labeling techniques. Herein, a new fluorescent photoswitch based on dicyano-vinyl modified difurylethenes was designed and prepared. This compound demonstrates typical reversible photochromism in solution and outstanding performance for the fluorescent detection of cyanide ions with excellent selectivity, sensitivity and high contrast. Furthermore, the mechanism of sensing toward cyanide ions was explained by 1H NMR titrations experiments. Owing to the strong fluorescence from a superior derivation with furan instead of thiophene, it is successfully applied as the fluorescent dyes and probe for detecting cyanide ions in vivo application.
