Organic polymeric bi-metallic composites
View Patent ↗Organic polymeric bi-metallic alkoxide or aryloxide composites are used as dielectric materials in various devices with improved properties such as improved mobility. These composites comprise a poly(meth)acrylate or polyester having metal coordination sites, and the same or different bi-metallic alkoxide or aryloxide molecules that are coordinated with the organic polymer. The bi-metallic alkoxide or aryloxide molecules can be represented by Structure (I) shown herein. Such composites are generally soluble at room temperature in various organic solvents and be provided in homogeneous organic solvent solutions that can be suitably applied to a substrate to form dielectric materials.
1. An organic polymeric bi-metallic alkoxide or aryloxide composite, comprising:
a poly(meth)acrylate or polyester comprising metal coordination sites, and
one or more of the same or different bi-metallic alkoxide or aryloxide complexed molecules that are coordinated with the poly(meth)acrylate or polyester, the bi-metallic alkoxide or aryloxide complexed molecules being selected from the group consisting of barium titanium (methoxyisopropanol) 6 , barium titanium (triethylene glycol ethyl ether) 6 , strontium titanium (methoxyisopropanol) 6 , and barium titanium (diethylene glycol monoethyl ether) 6 .
2. The organic polymeric hi-metallic alkoxide or aryloxide composite of claim 1 comprising a poly(meth)acrylate or a copolymer derived at least in part from an alkyl (meth)acrylate.
3. A homogeneous organic solvent solution of an organic polymeric bi-metallic alkoxide or aryloxide composite that is dissolved at room temperature within an organic solvent medium, comprising:
an poly(meth)acrylate or polyester comprising metal coordination sites, and
one or more of the same or different bi-metallic alkoxide or aryloxide complexed molecules that are coordinated with the poly(meth)acrylate or polyester, the bi-metallic alkoxide or aryloxide complexed molecules being selected from the group consisting of barium titanium (methoxyisopropanol) 6 , barium titanium (triethylene glycol ethyl ether) 6 , strontium titanium (methoxyisopropanol) 6 , and barium titanium (diethylene glycol monoethyl ether) 6 .
4. The homogeneous organic solvent solution of claim 3 , wherein the organic solvent medium comprises one or more organic solvents selected from the group consisting of anisole, toluene, any xylene, N,N-dimethyl formamide, dimethyl sulfoxide, tetrahydrofuran, 1-methoxy-2-propanol, 2-methoxyethanol, 1,2-dichloroethane, methylene chloride, chloroform, chlorobenzene, and 1,2,-dichlorobenzene.
