Aromatic polyazomethines (PAMs) are well known for their exceptional thermal, mechanical, and optoelectric properties. However, aromatic PAMs have limited practical industrial applications owing to their high melting temperature and low solubility in organic solvents. On continuing effort to improve the solubility of aromatic PAMs, in this study, we have synthesized aromatic poly(azomethine ether)s (PAEs) via polycondensation of 2,5-diformylfuran with ether linkage-containing aromatic diamine monomers in mild conditions. The molecular structures are investigated by 1H-NMR and FT-IR spectroscopy. The solubility and inherent viscosity are tested in commonly used organic solvents. The thermal transition and stability are analyzed by DSC and TGA, respectively. The optical properties are also investigated by UV-vis spectroscopy.
