One transistor for all purposes

Organic semiconductors

22-Mar-2019

In mobiles, fridges, planes – transistors are everywhere. But they often operate only within a restricted current range. LMU physicists have now developed an organic transistor that functions perfectly under both low and high currents. Transistors are semiconductor devices that control voltage ...

Semiconductors: No support needed

Scientists at LMU are the first to fabricate freely suspended, ultrathin, organic semiconductor films

08-Mar-2019

In recent years, interest in the investigation of several organic semiconductor materials has steadily increased. These compounds promise easier and cheaper fabrication without the need for scarce elements, as well very favorable electrical switching characteristics and correspondingly high ...

Solid-state catalysis: Fluctuations clear the way

19-Feb-2019

LMU chemists have identified a mechanism that allows molecules to diffuse rapidly on the already crowded surface of a solid-state catalyst – an important capability, especially for efficient catalysis under industrial conditions. The use of efficient catalytic agents is what makes many technical ...

Molecular motors: Chemical carousel rotates in the cold

26-Nov-2018

LMU chemists have developed the first molecular motor that can be powered by light alone. Its operation is therefore essentially independent of the temperature. Molecular motors, which rotate unidirectionally in response to an external energy input, constitute an important class of components for ...

All-in-one light-driven water splitting

10-Sep-2018

Solar-powered water splitting is a promising means of generating clean and storable energy. A novel catalyst based on semiconductor nanoparticles has now been shown to facilitate all the reactions needed for “artificial photosynthesis”. In the light of global climate change, there is an urgent ...

Biomimetic chemistry: Carbohydrate capture

27-Aug-2018

LMU chemist Professor Ivan Huc, who heads a research group devoted to the study of Biomimetic Supramolecular Chemistry, has designed and synthesized a molecular structure which features a helical binding pocket that is made-to-measure for the recognition and capture of xylobiose, a member of the ...

Chemical motors: Homing in on the hula twist

02-Jul-2018

The hula twist is no longer an unproven postulate: LMU chemists have now directly shown that a light-sensitive molecule can perform this complex photoreaction. This has inter alia implications for the development of novel molecular machines. Light-sensitive molecules, which alter their spatial ...

The biological role of europium

14-Jun-2018

Rare earth elements (REEs) are an indispensable component of the digital technologies that are now an integral part of our everyday life. Yet their biological role has been discovered only recently. A few years ago it became apparent that these metals are essential elements for methano- and ...

Biomimetic chemistry

04-Apr-2018

Not only can synthetic molecules mimic the structures of their biological models, they can also take on their functions and may even successfully compete with them, as an artificial DNA sequence designed by LMU chemist Ivan Huc now shows. Chemist Ivan Huc finds the inspiration for his work in the ...

A Keen Sense for Molecules

27-Feb-2018

Laser physicists from the Laboratory of Attosecond Physics at the Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics have developed an extremely powerful broadband infrared light source. This light source opens up a whole new range of opportunities in medicine, life ...
