The synthesis, property evaluation, and single crystal X-ray structures of four 5,7,12,14-tetrafunctionalized diazapentacenes are presented. The synthesis of these compounds either starts from tetrabromo-N,N-dihydrodiazapentacene or from a diazapentacene tetraketone. Pd-catalyzed coupling or addition of a lithium acetylide gave the precursors that furnish, after further redox reactions, the diazapentacenes as stable crystalline materials. The performance of the tetraphenyl-substituted compound as n-channel semiconductor was evaluated in organic field effect transistors.
本文介绍了四种 5,7,12,14-四官能化二氮杂戊并菲的合成、性质评估和单晶 X 射线结构。这些化合物的合成要么从四溴-N,N-二氢二氮杂戊并菲开始，要么从二氮杂戊并菲四酮开始。钯催化偶联或添加一个锂炔基得到前体，然后经过进一步的氧化还原反应，得到二氮杂戊并菲作为稳定的结晶材料。四苯基取代化合物作为 n 通道半导体的性能在有机场效应晶体管中进行了评估。
