説明
We synthesized cyclic π-conjugated molecules by double Friedel–Crafts reaction of amino group-substituted 1,2-bis(2-phenylethynyl)benzene with Meldrum’s acid derivative. The structures of the cyclic π-conjugated molecules were determined by single-crystal X-ray structure analysis. The oxidation of the dimethylamino group-substituted π-conjugated molecule with NOBF_4 gave a closed-shell dication that is stable at >210 °C. The monoradical cation of the di(4-methoxyphenyl)amino group-substituted π-conjugated molecule is stable in dichloromethane solution (half-life of nearly 15 days) and shows near-infrared absorption.
