In this study, we report the synthesis
of a series of planar and
helical dinaphthophenazines by cyclocondensation reactions between
the newly developed 9,10-bis((triisopropylsilyl)ethynyl)anthracene-1,2-dione
and different diamines. Their optoelectronic and electrochemical properties
are studied by ultraviolet–visible (UV–vis) spectroscopy,
fluorescence spectroscopy, cyclic voltammetry, and density functional
theory calculations.
