  • Patent number: 7135242
    Abstract: An electroluminescent polymer which has repeating units represented by formula (1) is obtained by polymerizing a bisfluorenylsilane compound which has specified substituent groups. In spite of the fact that this electroluminescent polymer is a ?-? conjugated type fluorene polymer, the deterioration in the color purity of EL caused by excimer formation is suppressed, so that the color purity of blue emitted light in particular is extremely high. This electroluminescent polymer is extremely useful as a light-emitting material in organic electroluminescent elements.

  • Patent number: 6607867
    Abstract: The present invention relates to norbornene monomers with a novel functional group containing an organometal as shown in the following Formula (I) or (II), a photoresist containing its polymers, manufacturing method thereof, and a method of forming photoresist patterns. Unlike existing polymers for photoresist matrix, polymers made by norbornene monomers described in the present invention is a chemical amplification type induced by photosensitive acids and can result in difference in silicon content between the exposed area and unexposed area due to dissociation of side chain containing silicon. The difference in the silicon content results in different etch rate with respect to oxygen plasma which makes dry developing possible.
