Conjugated polyazines have been receiving attention due to their semi-conducting and non-linear optical properties, making them potential candidates for electro-optical and optical applications. In this paper, an efficient polycondensation of á,ù-diformyl functional aromats, namely 2,5-diheptyloxy-1,4-diformyl benzene and side-chain substituted á,ù-diformyl oligo(p-phenylene vinylene) (OPV) with hydrazine afforded two novel conjugated polymers. Structurally, the resulting materials are rigid-rod type polymer chains that feature extended delocalized conjugated systems with integrated azine linkages. The polymer products were analyzed in regard to microstructure, chain length, and their optical properties. 1H/15N NMR and ATR-FTIR indicated all-trans configured C=N-N=C linkages in OPV-based azine polymers. The optical properties proved extended conjugation, and differential pulsed voltammetry showed that the OPV-based polyazine behaves as n-doped material.
