Organic Semiconductors

The European Patent Office (EPO) announced the winners of the European Inventor Award 2021, its prestigious annual innovation prize.  The individuals and teams were recognised for their innovative contributions in the fields of nasal drug delivery, DNA-based data storage, nanomaterials in dentistry, more

What is already established for inorganic semiconductors stays a challenge for their organic counterparts: Tuning the energy gap by blending different semiconducting molecules to optimize device performance. Now, scientists from TU Dresden, in cooperation with researchers at TU Munich, as well as Un more

The European Patent Office (EPO) announces that German scientist, professor and entrepreneur Karl Leo has been nominated as a finalist in the "Lifetime achievement" category of the European Inventor Award 2021. Leo's pioneering work with organic semiconductors led to the development of highly-effici 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
