Abstract

We elucidated that hexaalkoxytriphenylenes (HATs) are useful as a hole transport layer (HTL) in organic light emitting diodes (OLEDs). In particular, the insertion of a thin phthalocyanine layer between the anode and HTL drastically improved electroluminescent (EL) performance. Furthermore, we observed that the alkyl chain length of HATs greatly affected carrier transport and EL properties.
