Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Organic Electronics called Universally applicable small-molecule co-host ink formulation for inkjet printing red, green, and blue phosphorescent organic light-emitting diodes, Author is Liu, Lihui; Chen, Dingfu; Xie, Juxuan; Piao, Junxian; Liu, Yadong; Wang, Wei; Cao, Kun; Chen, Shufen, which mentions a compound: 435294-03-4, SMILESS is CC1=O[Ir+3]23([N]4=CC=C(C=CC=C5)C5=C4C6=CC=CC=[C-]36)(O=C(C)[CH-]1)[N]7=CC=C(C=CC=C8)C8=C7C9=CC=CC=[C-]29, Molecular C35H27N2O2Ir, Application In Synthesis of Bis[2-(1-isoquinolinyl-N)phenyl-C](2,4-pentanedionato-O2,O4)iridium(III).
For organic light-emitting diodes (OLEDs), inkjet printing technol. is being developed as an alternative to the traditional vacuum evaporation, because of its precise patterning, high-efficient material utilization, large-area compatibility and low-cost. In this work, we report a universal ink formulation of small-mol. co-host and binary solvents for red, green and blue phosphorescent OLEDs. Moreover, the effect of hole-transporting layers on the ink spreading, film uniformity and exciton confinement ability is investigated. Furthermore, a large-area (170 mm × 170 mm) and homogeneous light-emitting film is inkjet-printed. Finally, red, green and blue OLEDs are successfully constructed using these optimized ink formulations on the solvent resistance hole-transporting layer. This work can reduce the complexity to adjust the host materials and solvents for different color inks, and could be applied in large-area and low-cost OLED displays with high resolution
