“…Nano particle-immobilized LBL membranes, for example, can be applied to electrochromic devices. 28 Polysaccharides, 29 Cu(II) ions 30,31 and Ru(bpy)3 2+ ions 32 have been immobilized in LBL or PIC membranes. From these reports, it has been found that small molecules can be immobilized in polyelectrolyte complexes.…”

The immobilization of biomolecules is an important technique for bio-analysis, and can be applied to biosensors with both high selectivity and high sensitivity. Many researchers have developed immobilization techniques to optimize these characteristics. In the last two decades, an immobilization technique that meets the desired requirements was developed by using polyelectrolytes to form complexes, based on the electrostatic binding between polycations and polyanions. This review summarizes the techniques used for the immobilization of biomolecules by polyelectrolyte complexes; it also discusses related subjects.

“…DNA-based BioLEDs previously reported 4,5 have incorporated DNA-based thin films as hosts for lumophores indicating the feasibility of the concept, but without significant improvement in device performance over conventional OLEDs. Hirata et al have investigated 6 the properties of DNA as a charge transport layer in several device configurations elucidating their properties through their effect on the device current-voltage ͑I-V͒ characteristics.…”

Enhanced electroluminescent efficiency using a deoxyribonucleic acid ͑DNA͒ complex as an electron blocking ͑EB͒ material has been demonstrated in both green-and blue-emitting organic light-emitting diodes ͑OLEDs͒. The resulting so-called BioLEDs showed a maximum luminous efficiency of 8.2 and 0.8 cd/ A, respectively. The DNA-based BioLEDs were as much as 10ϫ more efficient and 30ϫ brighter than their OLED counterparts.

“…To overcome this drawback, some chemical methods, for example, enhancing charge mobility by adding charge transporting moieties at the ligands or incorporation of the Ru 2ϩ complex into the functional polymer, have been carried out. 9,12,18 There are few reports of device fabrication using ͓Ru(L) 3 ͔ 2ϩ complexes. 10,13,19 In this article, we report the properties of a light-emitting device fabricated using ruthenium(II)(4,7-diphenyl-1, 10-phenanthroline) 3 (͓Ru(dphphen) 3 ͔ 2ϩ ) complex in a ITO/͓Ru(dphphen) 3 ͔ 2ϩ /Ag structure.…”

Light-emitting devices based on ruthenium(II)(4,7-diphenyl-1,10-phenanthroline)3 ([Ru(dphphen)3]2+) as emitter have been fabricated. The effect of an electron transport layer of tris-(8-hydroxyquinoline) aluminum (Alq3) on device performance has been investigated. The emission, peaking at 630 nm, for the indium–tin–oxide (ITO)glass/[Ru(dphphen)3]2+/Ag device reaches maximum luminance after about 15 min at a turn on voltage of 2.5 V. The use of an ITO/[Ru(dphphen)3]2+/Alq3/Ag device reduces this response time to about 120 s at a turn on voltage of 7 V. A maximum brightness of 1300 cd/m2 can be obtained at 15 V within 2 s, with a luminous efficiency of 0.27 cd/A. Based on the charge transporting characteristics of [Ru(dphphen)3]2+ and Alq3 films determined by surface photovoltage spectroscopy, the improved device response time and efficiency are attributed to the enhanced electron injection at [Ru(dphphen)3]2+/Alq3 interface.
