通过二炔基异苯并呋喃和1,4-萘醌的[4 + 2]环加成，建立了合成5,6,11,12-四（芳乙基）四烯π-扩展rubrenes的新路线。在还原芳构化后，双亲核加成的芳基乙基在四烯丙烯酮上的引入得到了空间拥塞的芳基乙基四烯。并对新制备的π共轭分子的光物理性质进行了评价。
A new synthetic route to 5,6,11,12-tetrakis(arylethynyl)tetracenes, π-extended rubrenes, was developed via [4 + 2] cycloadditions of dialkynylisobenzofuran and 1,4-naphthoquinone. Introduction of arylethynyl groups by double nucleophilic additions to tetracenequinone gave sterically congested (arylethynyl)tetracenes after reductive aromatization. The photophysical properties of the newly prepared π-conjugated molecules are also evaluated.
