Newly synthesized red It complexes tris[2-(4-n-hexyl-phenyl)quinoline]iridium(III) and tris[(4-n-hexylphenyl)isoquinoline)]iridium(III) with long alkyl side chains are utilized to demonstrate the high efficiency multi-layer solution-processed red organic light-emitting diodes. Solubilities of these triplet emitters are high which enable them to be uniformly dispersed in the polymer host. Blade coating method is utilized to prepare organic multi-layers without mutual dissolution between different layers. 17 cd/A current efficiency, 10 lm/W power efficiency, and 8.8% external quantum efficiency can be achieved for the device with CsF/Al cathode. 10,000 cd/m(2) is reached at 10 V. Similar quantum efficiency is also achieved with an electron-transport layer and LiF/Al cathode. (C) 2010 Elsevier B.V. All rights reserved.

As the viewing devices for augmented reality (AR) shift from head-mounted display to smart devices, screen becomes a design factor which affects the viewing experience and associated conceptions. In this paper, we present three models of smart-device-based augmented reality (SDAR) for applications in interior design. The objective is to provide a theoretical framework for the rethinking of augmented reality based on relationships among screen, body, space and information, leading to developments in SDAR-assisted design for interior design profession.

The influence of the iridium complex solubility on the efficiency of multi-layer solution-processed organic light-emitting diode is demonstrated by synthesized orange triplet iridium complexes with the same core. The solubility of the iridium(III) bis(4-phenylthieno13,2-clpyridinato-N,C(2)') acetylacetonate is increased and uniform dispersion of iridium complex in polymer host poly(vinylcarbazole) is achieved by tert-butyl and n-hexyl group modification. Blade coating technique is utilized to achieve tri-layer structures with a polymer hole-transporting layer poly[(9,9-dioctylfluoreny1-2,7-diyl)-co-(4,4'-(N-(4-s-butylphenyl))diphenylamine)] a host-guest emissive layer, and small-molecule hole-blocking layer 1,3,5-tris(N-phenylbenzimidazol-2-yl) benzene. The efficiency as high as 20 cd/A is achieved for orange-emitting device. (C) 2010 Elsevier B.V. All rights reserved.
