Construction of Anthracene Bisimide-based Donor-Acceptor-Donor Arrays with 6,13-Diethynylpentacenes and 9,10-Diethynylanthracenes as Extended pi-Conjugated Systems
Donor-acceptor-donor arrays based on an anthracene bisimide (ABI) skeleton appended with 6,13-diethynylpentacene and 9,10-diethynylanthracene units have been constructed by Sonogashira coupling followed by reductive aromatization. Their photophysical and electrochemical properties are compared with those of the corresponding mono-substituted analogs on the basis of theoretical calculations and cyclic voltammetry to evaluate the intramolecular electronic interactions between ABI as the acceptor unit and diethynylacene as the donor unit.
