THIN-FILM LIGHT-EMITTING DEVICES FROM AN ELECTROLUMINESCENT RUTHENIUMCOMPLEX

A ruthenium polypyridyl complex has been synthesized and examined as a n emitter material in thin film electroluminescent devices. This mater ial exhibits photoluminescent and electroluminescent effects as well a s several reversible one-electron oxidation and reduction processes. E lectroluminescent devices fabricated from this ruthenium complex eithe r via spin coating methods or self-assembly techniques exhibit relativ ely high electroluminescent efficiencies and luminance levels in some cases as high as 100 cd/m(2).
