“…In mixtures with different phenolic group containing chromophores, the formation of ionic complexes was observed. [34][35][36][37][38] Because of deprotonation, the chromophores exhibited a bathochromic shift of their longest wavelength absorption band by more than 100 nm. Additionally, third-order nonlinear optical activity was evidenced on solution-cast films.…”

4-(Iminomethyl)phenol and 4-(iminomethyl)benzoic acid terminated aliphatic polyethers were obtained by conversion of Jeffamines with respective aromatic aldehydes. Mixtures of these polymers with polyamidines showed improved compatibility or even complete miscibility because of ionic complexes formed between the end groups of the modified polyethers and the basic amidine groups. Depending on composition and molecular weight of the components, blends with two or one glass transitions were obtained. In the case of 4-(iminomethyl)phenol terminated polyethers, deprotonation of the end groups resulted in a distinct change of the UV/vis absorption spectrum. This spectral alteration is discussed with respect to quantification of interactions in polymer blends.

“…It is known that hydrogen-bonded polymer networks formed in the interaction of polymers of the polyamidine type with dyes of the bisphenol type can also exhibit nonlinear optical properties [2]. Therefore, a study of the supramolecular structure of these polymer systems is of particular interest.…”
