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
介绍了四种 5,7,12,14-四官能化二氮杂五苯的合成、性能评价和单晶 X 射线结构。这些化合物的合成要么从四溴-N,N-二氢二氮杂五苯开始,要么从二氮杂五苯四酮开始。钯催化的偶联或乙炔锂的加成得到前体,在进一步的氧化还原反应后,二氮杂五苯成为稳定的结晶材料。在有机场效应晶体管中评估了四苯基取代化合物作为n沟道半导体的性能。
