A new approach captures ultra-thin pentacene film growth in real time, explaining the origin of grooves at silica–gold electrode interfaces. Imagine being able to follow individual molecules as they ...

Solar cell efficiency is limited because light at wavelengths shorter than the cell’s absorption threshold does not channel any of its excess energy into the generated electricity. Congreve et al.

As the price of energy continues to rise, businesses are looking to renewable energy for cheaper sources of power. Making electricity from the most plentiful of these sources - the sun -can be ...

Due to their high hole mobility, pentacene and its derivatives have been the representative organic semiconductors and have been the subject of much research, both basic and applied. In particular, ...

This is 9,10,11,20,21,22-hexaphenyltetrabenzo[a,c,l,n]pentacene, the most highly twisted polycyclic aromatic hydrocarbon ever prepared. Its X-ray structure shows an end-to-end twist of 144°. Unlike ...

Growth of pentacene on well-ordered self-assembled monolayers enable the realization of high performance organic transistors. Organic semiconductors offer the promise of inexpensive and easier to ...

University of Rochester physicists have learned why Pentacene, the leading candidate for developing organic semiconductors, conducts electricity in inconsistent ways rather than with predictable ...

The above image is a photo of a pentacene molecule. Not a drawing. A photo. Taken by researchers at IBM’s Zurich lab. The tip of this microscope employs one oxygen atom bonded to one carbon atom. It’s ...

Light instability is a major factor preventing organic semiconductors from being implemented. Researchers from Osaka Metropolitan University demonstrated the ultrafast intersystem crossing of the ...

Thanks to specialised microscopes, we have long been able to see the beauty of single atoms. But strange though it might seem, imaging larger molecules at the same level of detail has not been ...

Improving the efficiency of converting sunlight into electricity is a fundamental task if humanity is to overcome its dependence on fossil fuels. When light is shone onto a semiconductor, for example ...

If you've ever taken a chemistry class, you have seen plenty of diagrams of molecules. If you made it to organic chemistry, you fiddled with one of the tinker-toy-like molecule kits, building your own ...
