In this paper, coumarin 6 was selected as the main ligand owing to its advantages of simple synthesis, high yield, and excellent luminescence stability. Two ionic phosphorescent iridium(III) complexes (Ir-TPIP/Ir-TPHIP) were synthesized by introducing triphenylamine moiety into imidazo[4,5-f][1,10]o-diazaphene and accessing a hexane chain at the imidazole as the two auxiliary ligands, respectively, both Ir-TPIP and Ir-TPHIP exhibit orange light with the maximum emission wavelengths of 564 and 585 nm in solution, respectively. Subsequently, Ir-TPIP/Ir-TPHIP-based orange OLEDs were prepared by the solution method, and the maximum brightness of the devices were 3038/1045cd/m<sup>2</sup>, with corresponding maximum CEs, PEs, and EQEs values of 4.13/4.45 cd/A, 0.79/0.87 lm/W and 1.81/1.87 %, respectively.</div></div>","PeriodicalId":13609,"journal":{"name":"Inorganic Chemistry Communications","volume":"178 ","pages":"Article 114477"},"PeriodicalIF":4.4,"publicationDate":"2025-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143791373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
