Abstract: Two symmetrically substituted phenylenevinylene D-A-D′-A-D type siblings, (2Z,2′Z)-2,2′-(2,5-dimethoxy-1,4-phenylene)bis(3-(4-(dimethylamino)phenyl)acrylonitrile) (↑-dscn) and (2Z,2′Z)-3,3′-(2,5-dimethoxy-1,4-phenylene)bis(2-(4-(dimethylamino)phenyl)acrylonitrile) (↓-dscn), are prepared. We investigate the effect of different but symmetrical location of these cyano groups in vinylene bridges on the 1-photon and 2-photon… read more here.

DOI: 10.1246/cl.170381
Abstract: Effects of a small functional group, cyano, on the supramolecular polymerization of fan-shaped monomers were investigated. When cyano groups are replaced by hydrogen atoms, the resultant monomers surprisingly fail to undergo supramolecular polymerization and exist… read more here.
