Researchers have discovered a way to stop the quantum dance of atoms 'seen' by electrons in carbon-based organic molecules. This development will help improve the performance of light emitting molecules used in displays and bio-medical imaging.
Now, researchers using laser-based spectroscopic techniques have discovered 'new molecular design rules' capable of halting this molecular dance. Their results, reported in, revealed crucial design principles that can stop the coupling of electrons to atomic vibrations, in effect shutting down their hectic dancing and propelling the molecules to achieve unparalleled performance.
To demonstrate these design principles, the scientists designed a series of efficient near-infrared emitting molecules. In these molecules, energy losses resulting from vibrations -- essentially, electrons dancing to the tune of atoms -- were more than 100 times lower than in previous organic molecules.
