A series of simple donor-acceptor mols. consisting of an oligo-oxyethylene (OOE) N-substituted diphenylamine connected to a dicyanovinyl (DCV) acceptor group by a thienyl π-conjugating spacer are synthesized. Amorphous deep-red freshly cast thin films rapidly evolve towards an almost colorless pale beige poly-crystalline stable material from which a deep-red photoluminescent state can be switched-on by mech. stimulation. The effects of the length of the OOE chain on the mol. packing of the material and on the dynamics of the recovery process and aggregation in solution are analyzed. Crystallog. results show that the length of the OOE chain directly controls the mol. packing from head-to-tail arrangement of the dipoles for short chain to co-facial dimers leading to a non-centrosym. material with nonlinear optics (NLO) activity for the longer ones. The anal. of the dynamics of the self-recovery process of thin films and of mol. aggregation in solution shows that the dynamics of both processes is directly controlled by the length of the OOE chain. Since, as confirmed by optical and electrochem. results, the OOE substituents have strictly no influence on the electronic properties of the π-conjugated system, the observed effects are unambiguously related to changes in intermol. interactions.
