Single-layer polymer light-emitting field-effect transistors (LEFETs) that yield EQEs of >8% and luminance efficiencies >28 cd A(-1) are demonstrated. These values are the highest reported for LEFETs and amongst the highest values for fluorescent OLE

We investigate the influence of small amounts of semiconducting single-walled carbon nanotubes (SWNTs) dispersed in polyfluorenes such as poly(9,9-di-n-octylfluorene-alt-benzothiadiazole (F8BT) and poly(9,9-dioctylfluorene) (F8) on device characteris

Doping of organic semiconductors (OSCs) with transition metal oxides such as molybdenum trioxide (MoO3) has been used as a powerful method to overcome common issues such as contact resistance and low conductivity, which are limiting factors in organi

Electron injection from the source-drain electrodes limits the performance of many n-type organic field-effect transistors (OFETs), particularly those based on organic semiconductors with electron affinities less than 3.5 eV. Here, it is shown that m

Solution processing of polymer semiconductors provides a new paradigm for large-area electronics manufacturing on flexible substrates, but it also severely restricts the realization of interesting advanced device architectures, such as lateral hetero

Ambipolar light-emitting field-effect transistors (LEFETs) based on poly(9,9-dioctylfluorene-alt-benzothiadiazole) (F8BT) are able to combine electrical switching capability with the generation of light within a well-defined recombination zone inside

Ambipolar light-emitting organic field-effect transistors (LEFETs) possess the ability to efficiently emit light due to charge recombination in the channel. Since the emission can be made to occur far from the metal electrodes, the LEFET structure ha

In this communication, we report that dipotassium aryl bis(trifluoroborate)s make stable and easy-to-purify yet reactive monomers under Suzuki polycondensation reactions. A bis(trifluoroborate) of 2-alkylbenzotriazole was prepared successfully and co

Two novel conjugated copolymers based on alkylbenzotriazole and benzothiadiazole with high electron affinities are investigated for applications in polymer field-effect transistors and solar cells. The electron withdrawing nature of these polymers al
