Abstract 1-Bis [4-[N, N-di (4-tolyl) amino] phenyl]-cyclohexane (TAPC) has been widely used in xerography and organic light-emitting diodes (OLEDs), but derivatives are little known. Here, a new series of solution-processable, crosslinkable hole conductors based on TAPC with varying highest occupied molecular orbital (HOMO) energies from− 5.23 eV to− 5.69 eV is implemented in blue phosphorescent OLEDs. Their superior perfomance compared ...
