Engineering the spin-exchange interaction in organic semiconductors

Organic semiconductors based on molecular or polymeric π-conjugated systems are now used at scale in organic light-emitting diode (OLED) displays and show real promise in thin-film photovoltaics and transistor structures. Here, we address recent progress in understanding and performance for OLEDs and for organic photovoltaics.
