Bis(3-aminopropyl)-DDSQ was employed for polymerization with various aromatic dialdehydes to obtain poly(azomethine)s with high double-decker-shaped phenylsubstituted silsesquioxane (DDSQ) contents in the main chain. Introducing the flexible propylene linkers in the DDSQ unit provided flexible and optically transparent free-standing films. Their mechanical properties were highly dependent with the structures of the dialdehyde co-monomers.
