Abstract
Aromatic polyazomethines were prepared by the polycondensation of axially dissymmetric aromatic diamines and aromatic dialdehydes. The polycondensation of axially dissymmetric (R)- or (S)-binaphthyl-2,2′-diamines and aromatic dialdehydes in DMF at 100°C afforded wholly aromatic polyazomethines (Mn = 4600–7600), which are soluble in common solvents such as tetrahydrofuran. The combination of (R)- or (S)-6,6′-diamino-2,2′-dimethylbiphenyls and aromatic dialdehydes also yielded soluble wholly aromatic polyazomethines (Mn = 5500–12,000). Computational studies showed that the stable conformations of the polymers have one-handed helical structures. The chiroptical properties of the obtained polyazomethines were investigated based on circular dichroism (CD) spectra.
期刊介绍：
Journal of Polymer Research provides a forum for the prompt publication of articles concerning the fundamental and applied research of polymers. Its great feature lies in the diversity of content which it encompasses, drawing together results from all aspects of polymer science and technology.
As polymer research is rapidly growing around the globe, the aim of this journal is to establish itself as a significant information tool not only for the international polymer researchers in academia but also for those working in industry. The scope of the journal covers a wide range of the highly interdisciplinary field of polymer science and technology.
