Solution processable phosphorescent dendrimers based on cyclic phosphazenes for use in organic light emitting diodes (OLEDs).
A novel solution processable phosphorescent dendrimer based on cyclic phosphazene (CP) cores has been prepared and used as emissive layers in simple OLED architectures, providing efficiencies of 24.0 cd A(-1) and 16.7 lm W(-1).
متن کاملSolution-processable phosphorescent to organic light-emitting diodes based on chromophoric amphiphile/silica nanocomposite.
We report the synthesis of a tris-cyclometalated iridium complex which emits sky-blue light and its potential use in phosphorescent light-emitting devices. The hybrid meso-structured nanocomposites by sol-gel co-assembly with tetraethyl ortho-silicate and corresponding molecular interactions within mesopores were also demonstrated. Electroluminescent devices were fabricated using carbazole-base...
متن کاملContact Injection into Polymer Light-Emitting Diodes
The variation of current I with voltage V for poly(phenylene vinylene) and other polymer light-emitting diodes has been attributed to carriers tunneling into broad conduction and valence bands. In actuality the electrons and holes tunnel into polaron levels and transport is by hopping among these levels. We show that for small injection the I-V characteristic is determined mainly by the image f...
متن کاملPatterning polymer light-emitting diodes by micromolding in capillary
Here we describe a method of patterning electroluminescent (EL) polymers using micromolding in capillary (MIMIC). MIMIC is the one of the lithographic methods based on the microfludics among the soft lithography using a patterned poly(dimethylsiloxane) (PDMS) elastomer. The patterned microstructures of poly(dioctylfluorene) (PDOF), poly(p-phenylenevinylene) (PPV), and poly(2methoxy-5-2 0-ethylh...
متن کاملTemperature-dependent recombination in polymer composite light-emitting diodes
We study the temperature dependence of the current–voltage and radiance–voltage curves in double-carrier injected polymer light-emitting devices comprised of poly~2-methoxy,5~28-ethyl-hexoxy!– p-phenylene vinylene) ~MEH–PPV! and MEH–PPV/SiO2 as the active layer. The quantum efficiency increases significantly as the temperature is decreased in agreement with an increase in the recombination effi...
