Caption

Segmented polyurethanes (SPUs) that contain di-fluorenyl succinonitrile (DFSN) moieties and methacryloyl groups were synthesized. The obtained elastomers generated pink cyanofluorene radicals and changed color by compression or extension. This is the first example of force-induced cross-linking reactions achieved by only the extension or compression of a bulk film.
