The aim of this chapter is to present a simple but general band structure picture of the metal-semiconductor interface and compare that with the characteristics of the metal-conjugated polymer interface. The discussion is focused on the polymer light emitting diode (LED) for which the metal-polymer contacts play a central role in the performance of the device. The metal-polymer interface also applies to other polymer electronic devices that have been fabricated, e.g., the thin-film field-effect transistor3, but the role of the metal-polymer interface is much less cruical in this case and... 

Progress has been made in the search for new lanthanide /3-diketonates as sources of luminescence, with application in the fabrication of polymer light-emitting diodes for low-cost, full-color, flat-panel displays.16,17 Moreover, some complexes seem promising as chiral NMR reagents for the determination of enantiomeric purity18,19 and prospective catalysts in many organic syntheses.20... 

ZITO films with composition ZnIn2,oSni,502 have been prepared by CVD experiments employing [In(dpm)3], [Sn(acac)2], and [Zn(hfa)2(diamine)], (hfa = hexafluoroacetylacetonato). Such films were used in the fabrication of polymer light-emitting diodes, which exhibited light outputs and current efficiencies almost 70% greater than those of commercial Sn-doped indium oxide (ITO) films. ... 

Electroluminescence from Jt-conjugated polymers was first reported in 1990 by Burroughes et al. [1], Compared to inorganic materials and small molecules, polymers promise easy fabrication of large-area displays and illumination devices. In fact, the first flexible polymer light-emitting diode (LED) was demonstrated by Gustafsson et al. in 1992 [2]. 

In our first study [25], we sought to assess whether polymer light-emitting diodes could be used as a plug-in replacement for mercury lamp excitation in chip-based capillary electrophoresis systems. The microfluidic device was fabricated in glass using standard lithographic techniques, and is shown...

Poly(p-phenylenevinylene) derivatives are promising candidates for the active layer of polymer light-emitting diodes. Thus, various types of substituted poly(p-phenylenevinylene)s have been synthesized. Whereas these derivatives are soluble in organic solvents, a high-quality thin film of these polymers can be formed. Die optical properties of these polymers have been reviewed previously [8, 169]. The electroluminescence spectrum of the device fabricated with a conjugated pofymer is almost the same as that of the photoluminescence spectrum of the thin film of the polymer. The peaks in photoluminescence spectra are compiled in Table XVII [170, 171].
