摘要：

A series of aza[4]helicenes have been conveniently synthesized in yields of 71-92% by a one-pot procedure involving the Pictet-Spengler reaction. The structures of the aza[4]helicenes were characterized by H-1 and C-13 NMR spectroscopy, mass spectrometry, and X-ray crystallography. Moreover, it was found that the aza[4]helicenes self-assemble into 2D layers or herringbone-like structures in the solid state. In addition, the optical properties were investigated by UV and fluorescence spectroscopic methods.
