A novel synthetic route to diarylethenes fixed in a cyclopentene based on titanium-mediated carbonyl coupling leads to bis(3-thienyl)cyclopentenes that show photochromic behaviour similar to that of known diarylethenes.
A novel photoswitchablechemosensor for cyanideanionbased on dithienylethene unit was developed, which displayed excellent near‐infrared photochromism. Moreover, it presented a distinct triple sensing performance for CN– (colorimetric‐fluorescent‐colorimetric).
