Abstract: A light emitting device comprising a transparent substrate; a layer of conducting material in contact with the transparent substrate; a self-assembled monolayer bonded to the layer of conducting material; one or more light emitting polymer layers in electron contact to the self-assembled monolayer; and a reflective metal layer in electron contact with the light emitting polymer layer is provided. The light emitting device provided gives enhanced performance as compared to currently available devices. Also provided is a self-assembled monolayer having the formula: R2-R3—Y where Y is a group capable of electron contact with a light emitting polymer, R3 contains a conjugated group, and R2 is a group capable of bonding to a conducting material.

Abstract: Light emitting molecules and organic light emitting devices comprising such light emitting molecules are described. In one embodiment, a light emitting molecule comprises an anchoring group and a charge transport group having a first end and a second end. The first end of the charge transport group is bonded to the anchoring group. The charge transport group is configured to provide transport of electrical energy, and the transport of electrical energy is substantially one-dimensional. The light emitting molecule also comprises a light emissive group bonded to the second end of the charge transport group and a charge transfer group bonded to the light emissive group.
