Unique organic light-emitting molecular emitters
(PHYSorg.com Chemistry)

A team including researchers from Osaka University has produced a new molecular emitter for organic light-emitting diodes (OLEDs). Using rational chemical design with U-shaped synthetic building blocks, the scientists were able to arrange the electron donors and acceptors into a large ring called a `macrocycle.` The wheel-shaped molecule could potentially be used not only in OLEDs but also in tiny, energy-efficient chemical sensors in the future.
