Two-Step Synthesis, Structure, and Optical Features of a Double Hetero[7]helicene

A novel double aza-oxa[7]helicene was synthesized from the commercially available N(1),N(4)-di(naphthalen-2-yl)benzene-1,4-diamine and p-benzoquinone in two steps. Combining the acid-mediated annulation with the electrochemical sequential reaction (oxidative coupling and dehydrative cyclization) aff...

Sumario:A novel double aza-oxa[7]helicene was synthesized from the commercially available N(1),N(4)-di(naphthalen-2-yl)benzene-1,4-diamine and p-benzoquinone in two steps. Combining the acid-mediated annulation with the electrochemical sequential reaction (oxidative coupling and dehydrative cyclization) afforded this double hetero[7]helicene. Moreover, the structural and optical features of this molecule have been studied using X-ray crystallographic analysis, and the absorption and emission behaviors were rationalized based on DFT calculations.
