Nitrogen introduction of spirobifluorene to form α-, β-, γ-, and δ-aza-9,9′-spirobifluorenes: New bipolar system for efficient blue organic light-emitting diodes

Four aza-9,9′-spirobifluorenes (aza-SBFs) with nitrogen atom at different positions of one fluorene moiety were synthesized to study the structure-properties relationships. α-Aza-SBF and β-aza-SBF possessed almost completely separated the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO), while γ-aza-SBF and δ-aza-SBF showed overlapped HOMO and LUMO orbitals. The aza-SBFs showed excellent bipolar features and good thermal stabilities than those of SBFs. The maximum current efficiencies (CE) of α-, β-, γ-, and δ-aza-SBF-based OLEDs were 28.8, 24.9, 25.5, and 27.2 cd/A, respectively. Compared to the SBF, all of four aza-SBFs showed better devices performances. The CE and power efficiency (PE) of OLED based on α-aza-SBF was 28.8 cd/A and 22.6 lm/W, while the SBF-based OLED was only 12.3 cd/A and 8.2 lm/W. The maximum external quantum efficiency of α-aza-SBF-based OLED was 15.4%, which was 2.5 times than that of the SBF-based one (6.6%) due to introduction of nitrogen improving electron transporting. Novel materials based on these components and their potential applications in organic electronics were expected due to their excellent bipolar features.

Intramolecular Acylation of Unactivated Pyridines or Arenes via Multiple C-H Functionalizations: Synthesis of All Four Azafluorenones and Fluorenones

An unprecedented intramolecular acylation of unactivated pyridines via multiple C(sp3/sp2)-H functionalizations of a methyl, hydroxymethyl, or aldehyde group has been developed providing a general access to all four azafluorenones. The application of this protocol is further demonstrated to the synthesis of azafluorenone related fused nitrogen heterocycles and fluorenones. In addition, design and synthesis of a novel fluorene based organic emitter for potential use in organic light emitting devices (OLEDs) is also reported.
