Silicon-containing dendritic tris-cyclometalated Ir(iii) complex and its electrophosphorescence in a polymer host

In this paper, we present the synthesis and characterization of a new highly phosphorescent cyclometalated Ir(iii) complex with a silane-based dendritic substituent. The Ir(iii) complex showed 74 ± 3% of absolute phosphorescence quantum efficiency in the film state. In addition, efficient electrophosphorescence (32.8 cd A-1) employing an Ir(iii) complex-poly(N-vinylcarbazole) system device is observed. Study of a series of electroluminescent, spectroscopic, and electrochemical data of the Ir(iii) complex and the reference Ir(ppy)3 reveals superior performance of the new Ir(iii) complex.

A deep red phosphorescent Ir(III) complex for use in polymer light-emitting diodes: Role of the arylsilyl substituents

(Figure Presented) Here we report the synthesis and electrophosphorescence of a new deep-red phosphorescent Ir(III) complex with spatially embracing and thus solubilizing arylsilyl-substituted ligands, Ir(III) tris(2-(2′- benzo[b]thienyl)-5-(4′-triphenylsilylphenyl)pyridinato-N,C 3′). A poly(N-vinylcarbazole) (PVK) film doped with this Ir(III) complex exhibited excellent phase homogeneity and showed saturated red electrophosphorescence of 2.7% maximum external quantum efficiency, whose Commission Internationale de L'Eclairage coordinates were (0.69, 0.30).

Highly thermally-stable 4,4′-bis(4″-triphenylsilylphenyl)-1,1′- binaphthalene as the ultraviolet amplified spontaneous emitter, efficient host and deep-blue emitting material

We report herein the synthesis and characterization of an efficient versatile binaphthyl derivative, 4,4′-bis(4″-triphenylsilylphenyl)-1,1′-binaphthalene (SiBN) with a high glass transition temperature of 159.3 °C. Its role as a lasing dye was demonstrated by the amplified spontaneous emission, which exhibited an ultraviolet peak of 397 nm with a low threshold of 20 μJ/pulse. Meanwhile, the lasing film and blue electroluminescent device employing this novel binaphthyl derivative as the host showed superior performances to the reference based on the conventional host 4,4′-bis(carbazol-9-yl)biphenyl. Finally, extremely stable colour-tunable deep-blue (436 nm/472 nm) organic electroluminescent devices based on SiBN were demonstrated with very high brightness (>7521.2 cd/m2) and high external quantum efficiencies (1.90% for 436 nm and 4.66% for 472 nm emission). The development of such functional versatility materials will be an effective method for reducing the cost of organic photoelectric devices.
