Organic Semiconductors

Semiconductors made of organic materials, e.g. for light-emitting diodes (OLEDs) and solar cells, could replace or supplement silicon-based electronics in the future. The efficiency of such devices depends crucially on the quality of thin layers of such organic semiconductors. These layers are creat more

Doping is commonly used to improve performance in semiconducting devices but has not previously been successful for electron transporting or n-type, organic electronic materials. Now, an approach developed by KAUST uses a dopant, an additive that boosts the electronic performance and water stability more

For applications such as light-emitting diodes or solar cells, organic materials are nowadays in the focus of research. These organic molecules could be a promising alternative to currently used semiconductors such as silicon or germanium and are used in OLED displays. A major problem is that in man more

Recent theoretical studies show that charge transport in high-mobility organic semiconductors is limited by low-frequency vibrations because of strong non-local electron-phonon interaction. Here we investigate two high-electron-mobility organic semiconductors with similar molecular structures but co more

Here, we design and synthesize three new diketopyrrolopyrrole (DPP) derivatives with naphthalene, possessing large-scaled π-delocalized electronic structure, as the flanking groups and both linear (n-decyl and n-dodecyl) and branched (2-hexyldecyl) alkyl chains as substitutions as active layer for h more

Correction for ‘Diketopyrrolopyrrole based organic semiconductors with different numbers of thiophene units: symmetry tuning effect on electronic devices’ by Qian Liu et al., New J. Chem., 2018, DOI: 10.1039/c7nj03505e. more

Organic light-emitting device (OLED) is a solid-state light-emitting device based on organic semiconductors. Recent rapid advances in material chemistry have enabled white OLEDs to be used for general lighting and large-area flat panel displays. Efficacy of white OLED panel has reached 110 lm/W which exceeds that of fluorescent lamp. more
