The article contains the following contents:
Mechanochromic elastomers that exhibit force-induced crosslinking reactions in the bulk state are introduced. The synthesis of segmented polyurethanes (SPUs) that contain difluorenylsuccinonitrile (DFSN) moieties in the main chain and methacryloyl groups in the side chains was carried out. DFSN was selected as the mechanophore because it dissociates under mech. stimuli to form pink cyanofluorene (CF) radicals, which can also initiate the radical polymerization of methacrylate monomers. The obtained elastomers generated CF radicals and changed color by compression or extension; they also became insoluble due to the mech. induced crosslinking reactions. Addnl., an SPU containing diphenylmethane units also exhibited highly sensitive mechanofluorescence. To the best of our knowledge, this is the first report to demonstrate damage detection ability and changes in the mech. properties of bulk elastomers induced by simple compression or extension.5-Hexen-1-ol(cas: 821-41-0SDS of cas: 821-41-0) was used in this study.
5-Hexen-1-ol(cas: 821-41-0) is used in cyclization to a tetrahydropyran by phenylselenoetherification. It is also used as a building block in synthetic chemistry.SDS of cas: 821-41-0
