Novel Pt tetradentate complexes having Pt—O bond is disclosed. These complexes are useful as emitters in phosphorescent OLEDs.

The invention relates to a method for preparing a cellulose dope comprising mixing and dissolving the cellulosic raw material in dilute and concentrated aqueous organic solvent in a two-stage process to form a homogeneous slurry, followed by heating the homogeneous slurry to obtain a cellulose dope containing 11% to 20% cellulose by weight. The invention also relates to a cellulose dope comprising 11% to 20% cellulose by weight and 73% to 79% aqueous organic solvent wherein the concentration of the cellulosic and metallic impurities in the cellulose dope shows a percent reduction of 20% to 50% from the cellulosic raw material.
