Copper(I) complexes with thermal activated delayed fluorescence (TADF) have attracted considerable attention for the development of emissive materials in organic light-emitting devices. However, many emissive CuI complexes are cationic emitters and cannot be vacuum-sublimed, a process used for device fabrication. This has limited their applications in devices. In this work we have developed a series of emissive charge-neutral CuI complexes with the general formula [Cu(2,9-Me2phen)(CNR){CNB(C6F5)3}] [R = 2,6-Me2C6H3, 2,6-iPr2C6H3, 2,4,6-Cl3C6H2, 2,4,6-Br3C6H2, 3,5-(CF3)2C6H3, 4-SF5C6H4] through the incorporation of a strong π-accepting anionic isocyanoborate ligand. All the complexes have been structurally characterized and their photophysical properties have been studied.
