Festkörper‐Polymerisation eines ‘Push‐Pull’‐Diacetylens

Abstract

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.
