Efficient Red-Emitting Electrophosphorescent Polymers
We report the synthesis and characterization of a series of electrophosphorescent polymers with a polyfluorene backbone, containing a red-emitting iridium complex and carrier-transporting units as the substitutes of the C-9 position of fluorene. Different specimens and contents of the hole-transporting moieties were found to influence the electroluminescent properties of the polymers. Incorpora...

SYNOPSIS The statement made in some standard textbooksthatBenedict'squalitativetestgivesa green, yellow, or orange-red precipitate with pure solutions of glucose of varying strength has been shown to be incorrect. Pure solutions ofglucose give only a bright red precipitate at all concentrations. These changes in the colour of the suspensions are observed with urinary glucose only. The differenc...
متن کاملA high-efficiency and low-operating-voltage green electrophosphorescent device employing a pure-hydrocarbon host material.
A suitable triplet energy level and high morphological stability and hole mobility make indenofluorene an effective host material for green phosphorescent OLEDs.
