Organic spintronic devices and methods for making the same

摘要

An organic spintronic photovoltaic device (100) having an organic electron active layer (102) functionally associated with a pair of electrodes (104, 106). The organic electron active layer (102) can include a spin active molecular radical distributed in the active layer (102) which increases spin-lattice relaxation rates within the active layer (102). The increased spin lattice relaxation rate can also influence the efficiency of OLED and charge mobility in FET devices.

1. An organic spintronic device, comprising:
a) an organic electron active layer which is a bulk heterojunction including a donor material blended with an acceptor material, said organic electron active layer including a spin active molecular radical distributed in the organic electron active layer which increases spin-lattice relaxation rates within the organic electron active layer, wherein the acceptor material comprises a fullerene and the spin active molecular radical comprises galvinoxyl (2,6-Di-tert-butyl-α-(3,5-di-tert-butyl-4-oxo-2,5-cyclohexadien-1-ylidene)-ptolyloxy)and
b) a pair of electrodes functionally associated with the organic electron active layer to complete a circuit which transfers electrons via the organic electron active layer.
