The present invention relates to azaborinine derivatives of formulae (l-1) or (I-2), their synthesis as well as their use in organic electronic devices, particularly in organic light emitting devices such as OLEDS, organic photovoltaic devices and organic photodetectors. The invention further relates to organic electronic devices comprising the present azaborinine derivatives in devices such as e.g. OFET.
Using a concise synthetic strategy, a series of novel ladder-type BN-embedded heteroacenes were successfully synthesized. Their molecular skeletons render the versatile modification which is desirable for achieving unique physical properties. Organic light-emitting diode devices based on BN-embedded heteroacenes were subsequently fabricated, demonstrating their promising application as blue emitters.
