Coloration efficiency, ruthenium

A series of azodicarbonyl dinuclear ruthenium polymers were synthesized. Spectroscopic and electrochromic properties of these polymers were studied. These polymers were found to exhibit good thermal stability and electrochromic properties such as good coloration efficiency in the near infrared region. Furthermore, long-term switching trials were performed, which indicated good chemical stability of the material and potential application for attenuation of near infrared light. 

Well-known phosphorescent emitter devices are iridium(III) and platimnn(ll) complexes. When placed in a suitable host material (small molecules of polymeric materials), such emitters find applications in full-color displays. One of the main requirements for OLEDs doped with phosphorescent emitters is that the phosphorescent emitter should exhibit very high phosphorescence quantum efficiencies. Similar interesting properties are also displayed in many other metal complexes, such as osmium(II), rhemium(l), and ruthenium(II). Platimmi(ll) porphyrinas [141] or iridium(lll) complexes containing 2-phenylpylidine,...
