Abstract:
1. An electro-optic device, comprising: a first electrode; a second electrode spaced apart from said first electrode; and an active layer of organic semiconducting material between said first electrode and said second electrode, wherein said active layer comprises a quasi-bilayer in which a first plurality molecules from a first layer of active material is interpenetrated by a second plurality of molecules from a second layer of active material formed on said first layer, said first and second pluralities of molecules providing donor-acceptor pairs such that said quasi-bilayer has at least a portion that is a bulk heterojunction active layer, and wherein each of said first plurality of molecules has a long axis that is longer than corresponding transverse axes and said long axis is substantially aligned along a common direction such that said active layer is more sensitive to a first polarization of incident light than a second polarization of said incident light, said first polarization and said second polarization being orthogonal polarization components of said light.
