The non-emissive benzene ring and green-emissive arylmaleimide are employed as two independent cores to construct dual-core white star-shaped polymers (DC-PFMs). Due to the totally star-shaped structure, DC-PFMs display a higher quantum yield and ele

A new strategy to realize efficient white-light emission from a binary fluo- rene-based copolymer (PF-Phq) with the fluorene segment as a blue emitter and the iridium complex, 9-iridium(III)bis(2-(2-phenyl-quinoline-N,C 30 )(11,13-tetradecanedio- nat

A strategy to generate an efficient white-light emission has been developed by mixing fluorescence and phosphorescence emission from a single polymer. Fluorene is used as the blue-emissive component, benzothiadiazole (BT) and the iridium complex [(bt

It is therefore desirable to obtain white-light emission from a single-component material so as to avoid these drawbacks. In the past few years, studies in this field have attracted growing interest and encouraging progress has been made. Li et al. [

In this paper, two complexes (mppy) 2 Ir(tmd) and (bppy) 2 Ir(tmd) were synthesized and doped into PVK. We find that the alkyl substitution of bicycloiridium complexes on acetylacetonate ligand has a great effect on optimizing the PLED performances.

High-efficiency saturated red light-emitting polyelectrolytes and their neutral precursors: aminoalkyl-substituted polyfluorenes (PFN) with different 4,7-di-2-thienyl-2,1,3-benzothiadiazole (DBT) contents were synthesized by Suzuki coupling reaction.
