The present invention provides an electrophosphorescent organic light-emitting diode (OLED). The electrophosphorescent OLED includes a substrate having a first opposing surface and a second opposing surface, a first electrode layer overlying the first opposing surface, and a light-emitting element overlying the first electrode layer. The light emitting element includes a hole injection layer and a phosphorescent emissive layer. The hole injection layer is formed of a crosslinked polysiloxane, which includes at least one siloxane unit R&#x2014;Y&#x2014;Si&#x3b8;3/2 having at least one aromatic amine group (R) and at least one divalent organic group (Y). The aromatic amine group includes at least one of a carbazolyl group, a substituted carbazolyl group, a triarylamine group, and a substituted triarylamine group.

Electrophosphorescent organic light emitting diode formed using solvent soluble materials

A method of removing or recovering a volatile organopolysiloxane such as octamethylcyclotetrasiloxane (D.sub.4) from a fluid stream such as air, containing the volatile organopolysiloxane and a hydrocarbon, for example, by adsorbing the volatile organopolysiloxane on dry soil contained in a column, and allowing the remainder of the fluid stream including the hydrocarbon to pass through the column. The dry soil containing the adsorbed volatile organopolysiloxane and any degradation product(s) is then wetted by passing moist air, water, or steam, through the column to desorb, vaporize, and remove the volatile organopolysiloxane from the column. The column containing the wet soil can then be regenerated by air drying the wet soil, and the separating cycle is repeated.
