Dibenzo[n]phenecenes (DBnPs, n = 5–7) were conveniently synthesised through Mallory photocyclization as the key step. Effective mobilities of single-crystal field-effect transistors of DBnPs were evaluated to demonstrate that C2h-symmetrical DB6P shows higher performance than C2v-symmetrical DB5P and DB7P.
通过Mallory光环化反应很容易地合成了二苯并[ n ]苯并(DB n Ps,n = 5-7)。对DB n Ps的单晶场效应晶体管的有效迁移率进行了评估,以证明C 2h对称DB6P显示出比C 2v对称DB5P和DB7P更高的性能。
