1. A method of fabricating an organic light emitting device, comprising:
(a) depositing a first organic layer over a first electrode;
(b) depositing a second organic layer over and in physical contact with the first organic layer, wherein
(1) the second organic layer comprises a small molecule emissive material,
(2) the second organic layer is a patterned layer deposited by solution processing, and
(3) the first organic layer is insoluble in the solution used to deposit the second organic layer; and
(c) depositing a second electrode over the second organic layer.
