We investigate the modulation of the charge injection in organic field-effect transistors with self-assembled monolayers (SAMs) using both a bottom-gate and a top-gate geometry. The current modulation by using SAMs is more pronounced in the top-gate geometry due to the better defined upper surface of the bottom source and drain electrodes. By...

A study is carried out of the external quantum efficiency (EQE) of organic light-emitting diodes (OLEDs) based on blue-emitting fluorene polymers containing hole-transporting units. For that purpose, 10 polymers containing a systematically varied amount of two different (benzidine-based and phenoxazine-based) aromatic amine comonomers are...

Conjugated polymer-molecular dye blends of MDMO-PPV (poly[2-methoxy-5-(3′,7′-dimethyloctyloxy)-1,4-phenylenevinylene]) and PF1CVTP (poly[9,9-dioctylfluorene-2,7-diyl-alt-2,5-bis(2-thienyl-1-cyanovinyl)-1-(3′,7′-dimethyloctyloxy)-4-methoxybenzene-5″,5″-diyl]) with three dipyrrometheneboron difluoride (bodipy) dyes were studied by (time-resolved)...

It has recently been reported that, after electrical conditioning, an ohmic hole contact is formed in poly(9,9-dioctylfluorene) (PFO)-based polymer light-emitting diodes (PLED), despite the large hole-injection barrier obtained with a poly(styrene sulfonic acid)-doped poly(3,4-ethylenedioxythiophene) (PEDOTPSS) anode. We demonstrate that the...

Polymers with a small amount of dye blended in offer an attractive possibility to change the color of the emitted light by changing the dye. We present ab initio calculations within density-functional theory of the HOMO/ LUMO energies for dipyrrolomethane dyes, polyphenylenevinylene and polyfluorene. Special attention is paid to the trends in...

The mechanism of excitation energy transfer is studied using host-guest systems consisting of green and yellow emitting poly(phenylene vinylene) (PPV) based polymers into which red emitting dyes are dispersed. The photoluminescence from such polymer-dye systems is studied in the steady-state and time resolved. Furthermore, the...

Organic semiconducting materials are now being investigated as active materials in light emitting diodes, photovoltaic cells, plastic electronics, etc. Important issues concerning the materials common to all areas, are processability, purity, reproducibility, stability and control over morphology. Big improvement in device fabrication, initial...
