In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Chemically doped hole transporting materials with low cross-linking temperature and high mobility for solution-processed green/red PHOLEDs, published in 2020-07-01, which mentions a compound: 435294-03-4, mainly applied to doped hole transport material crosslinking temperature mobility phosphorescent LED, Computed Properties of C35H27N2O2Ir.
Recently, developing insoluble cross-linkable functional layers plays a vital role for solution-processed organic light emitting diodes (OLEDs). Here, 2 vinyl-based cross-linkable hole transporting materials V-TPAVTPD and V-TPAVCBP are designed and synthesized. Cationic photoinitiator 4-octyloxydiphenyliodonium hexafluoroantimonate (OPPI) is 1st introduced to chem. induce vinyl-based photo crosslinking process, aiming at lowering crosslinking temperature and enhancing hole mobility. Crosslinking can occur at expressly low temperature of 120° with >95% solvent resistance. Hole mobility is markedly enhanced with the value >10-3 cm2 V-1 s-1. When applying hole transporting layers (HTLs) to solution-processed green and red phosphorescent OLEDs, devices exhibit excellent properties. The maximum current efficiency of 54.0 cd A-1 (green), 9.8 cd A-1 (red) and external quantum efficiency of 15.5% (green), 15.0% (red) are obtained when OPPI doped V-TPAVCBP serves as HTL. This low temperature feasible crosslinking process to prepare HTLs with preferable hole mobility promotes the development of OLEDs.
