Abstract
Different from small-molecule multiple resonance emitters processed via vacuum evaporation technology, we present the design of multiple resonance dendrimers by introducing the first- and second-generation carbazole dendrons in periphery of boron, oxygen, nitrogen-doped polycyclic aromatic skeleton, for efficient narrowband blue electroluminescence by solution process. The multiple resonance dendrimers not only keep the narrowband emission of polycyclic aromatic skeleton, but also can suppress their intermolecular aggregation by steric carbazole dendrons, overcoming the unwanted spectral broadening in solid state. The resultant first-generation carbazole dendrimer exhibits narrowband blue emission with promising photoluminescenct quantum efficiency of 94% and delayed fluorescence with lifetime of 139.1 μs in solid-state film. Solution-processed organic light-emitting diodes based on the dendrimers reveal electroluminescence at 488 nm with full-width at half maximum of 39 nm, maximum luminous efficiency of 29.2 cd A-1 and maximum external quantum efficiency of 13.4%.
