A novel macrocycle containing tetrabenzeneaza was developed as a novel building block for hole transport materials (HTMs). Benefiting from its unique highly twisted spatial configuration, this macrocycle exhibits high triplet energy level (ET) as well as high hole mobility. Based on this aza macrocycle, 2 hole transporting materials, 2TPATPCA and 2CzTPCA, were designed and synthesized. Both 2TPATPCA and 2CzTPCA possess enough ETs, appropriate frontier orbital energy levels as well as good thermal stability, which promote them as universal HTMs in multicolor phosphorescent organic light-emitting devices (PhOLEDs) and thermally activated delayed fluorescence (TADF) OLEDs. High external quantum efficiencies (EQEs) were realized in OLEDs using the these 2 HTMs. For example, sky blue PhOLED with 2CzTPCA showed a significantly improved maximum EQE of 20.3% compared to that of the reference device using N,N’-Bis(naphthalen-1-yl)-N,N’-bis(phenyl)benzidine (NPB) (EQE of 14.2%) and 4,4′-Cyclohexylidenebis[N,N- bis(4-Me phenyl)aniline] (TAPC) (EQE of 12.2%). Green TADF OLED using 2CzTPCA as HTM also exhibit a much improved maximum EQE of 17.9% compared to that of the reference device based on NPB (EQE of 10.3%). These results indicate this tetrabenzeneaza macrocyclic is a promising building block for developing universal high-performance HTMs. In the experimental materials used by the author, we found 1-Bromo-3-iodobenzene(cas: 591-18-4Name: 1-Bromo-3-iodobenzene)
