In their electronically excited state Möbius aromatic molecules display “antiaromaticity,” characterized by high energy levels and high instability. To understand their properties, researchers in Japan applied a time-resolved electron paramagnetic resonance method to detect the magnetic properties of a reactive intermediate molecule hexaphyrin. Illuminating hexaphyrin with laser pulses, they detected the resonance between the microwave and the electron spins linked to the magnetism of the excited triplet state and to the external magnetic field. The findings has application in the use of these special properties to electronic functional materials, such as organic solar cells and electric conductors…read more. TECHNICAL ARTICLE
