pentacenequinone with TMSCF3 (Ruppert's reagent) and deprotection led to 6,13-bis(trifluoromethyl)pentacene-6,13-diol, which was aromatized to 6,13-bis(trifluoromethyl)pentacene by using PBr3. 6,13-Dialkoxypentacenes were accessible by alkylation of the corresponding hydroquinopentacenes by using dialkyl sulfates. 6,13-Bis(trifluoromethyl)pentacene and 6,13-dimethoxypentacene exhibit slipped face-to-face
合成了 6,13-二取代的并五苯。确定了它们的电化学和光学特性,以及它们在固态下的堆积基序。用 TMSCF3(鲁珀特试剂)处理并五苯醌并脱保护生成 6,13-双(三氟甲基)并五苯-6,13-二醇,使用 PBr3 将其芳构化为 6,13-双(三氟甲基)并五苯。6,13-二烷氧基并五苯可通过使用二烷基硫酸盐将相应的氢醌并五苯烷基化而获得。6,13-双(三氟甲基)并五苯和6,13-二甲氧基并五苯在固态下表现出滑动的面对面π堆积,而6,13-二乙氧基并五苯在固态下形成π堆积分子对。
