Abstract: A pixel structure for use in a white light emitting organic electroluminescent device therein comprises a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel. The first sub-pixel has a first color filter and a first color change medium. The second sub-pixel has a second color filter and a second color change medium. The third sub-pixel has only a third color filter. The fourth sub-pixel does not have any color filter or color change medium so that the white light emitted from the white light emitting organic electroluminescent device can pass through the fourth sub-pixel directly. Thereby, the white light can be transformed into the color corresponding to each color change medium. Besides, the color shown from the pixel structure can be modulated by the white light from the fourth sub-pixel.

Abstract: This invention provides a novel process for preparing soluble phthalocyanines by microwave irradiation in the absence of any organic solvent. Three different starting materials, i.e. t-butylphthalic anhydride, t-butyl phthalonitrile and metal-free H2Pc (tetra-t-butylphthalocyanine) have been adopted , respectively. The starting material with proper metal compound, such as chloride or acetate were irradiated in a commercial microwave oven for a period of 1 to 30 minutes at a power of 200˜900 W. This process is noted to reduce drastically reaction time of MPc formation from 8˜24 hours to 10˜30 minutes due to its unique heating by microwave irradiation. Sandwiched type MPc2(such as Lu Pc2) can be produced only through metal replacement from metal-free phthalocyanine by microwave irradiation.
