Abstract
•Polyketanils exhibit better conjugation than corresponding polyazomethines.•Modification of the N-phenyl ring causes minor changes in conjugation of polyketanils than in corresponding polyazomethines.•Replacement of the phenyl ring derived from diketone by the vinyl group improve the conjugation.
Conjugation effect in three series of polyketanils obtained from p-dibenzoylbenzene, 1,8-disebacoylbenzene or trans-1,2-dibenzoylethylene and proper diamines were studied using the FTIR spectra. Changes in conjugation caused by modification of the phenyl ring originating from diamine were analyzed and compared with these observed for corresponding polyazomethines. Obtained results were confirmed by the NMR spectra.
