Abstract

Much of the fascination in conjugated polymers stems from the realization of potential device applications,[1] yet the true power of these materials lies in the possibility to synthesize a compound with a particular property from first principles. A defining feature of these carbon- based semiconductors is that spin–orbit coupling is weak, thus making spin states welldefined.[2–3] Electrical injection of charges into an organic light-emitting diode (OLED ...
