Abstract
Recent advances in organic spin response have unraveled long polaron spin coherence time, substantive magnetic field effect (MFE) in organic light emitting diodes (OLED) and films, and spin-polarized carrier injection from ferromagnetic electrodes in organic spin valves (OSV). Here we compare spin response in films, OLED and OSV devices based on π-conjugated polymers made of protonated, and deuterated (D-) hydrogen having weaker HFI strength. We show that the HFI plays a crucial role in determining the spin response in all devices. OLEDs (and films) based on the D-polymers show substantial ...
