Purpose: The aim of this paper is to show results of optical measurement performed on poly - (1-(4-methylenephenoxy-1)phenylene-4-methylene-1.4-phenylnenitrylomethylene) (PPI2) polyazomethine thin films and to compare with poly - (1.4-phenylenemethylenenitrilo-1.4 phenylenenitrilomethylene) (PPI). Design/methodology/approach: Influence of oxygen atom in the polymer chain on optical properties of polyazomethine was investigated. Optical UV-VIS and FTIR absorption spectra of polyazomethine PPI2 with oxygen atom were recorded and X-ray patterns of these polymers were performed. Findings: The oxygen atom incorporated in ordered way into PPI2 chain breaks conjugation and cause increase of energy gap in polymer. Research limitations/implications: The oxygen atom incorporated between phenylene rings of dialdehyde changes PPI chain into sequence of alternative three ring conjugated fragments and oxygen atoms. Practical implications: Addition of oxygen atom inside aldehyde fragment in polyazomethine chain influences conformation of polymer. The prepared layers of polyazomethine with oxygen atom in the backbone are expected to be more amorphous and more luminescent properties. Originality/value: Polyazomethine is very interesting material as it has nitrogen atom in the backbone, and is isoelectronic counterpart of polyparaphenylenevinylene (PPV). This paper shows that addition of oxygen atom into polyazomethine chain influences its optical properties.
