Festkörper-Polymerisation eines ‘Push-Pull’-Diacetylens

Solid-State Polymerisation of a ‘Push-Pull’-Diacetylene Solid-state polymerisation of ‘push-pull’-diacetylene 5-(diphenylamino)-1-phenylpenta-2,4-diyn-1-one ( 1d ), initiated by heating of crystals of 1d at 90°, gives ‘push-pull’ poly-diacetylene 2d . X-Ray results and spectroscopic data of monomer 1d as well as of polymer 2d are discussed.
