摘要:
The invention is directed to a family of organo-metal complexes having a metal atom coordinated to charged fluorinated ligands and a neutral ligand or ligands. The metals may be lanthanide or transition metals. The complexes according to the invention are of general formula MA x B y , where A is a charged ligand; B is a neutral ligand; x=the valence of metal M, typically +3 for lanthanides and +2 or +3 for transition metals; and y=0-3. Typically, for lanthanide metals y=1 or 2 and for transition metals y=0 or 1, although higher values of y can be attained in both cases. Suitable neutral ligands include dimethyl sulfoxide, glyme, and di-, tri- and tetra-glyme. The charged ligands are fluorinated charged ligands selected from the group consisting of and mixtures thereof.
摘要:
Disclosed are novel light polarizing articles comprising a substrate (101), a light polarizing layer (11), an inorganic intermediate layer (107) between the polarizing layer and the substrate, an optional inorganic sub-layer (105) between the substrate and the inorganic intermediate layer, and a protective layer (113) over the light polarizing layer, and method of making the same. Due to the presence of the inorganic intermediate layer and the optional sub-layer, adhesion of the polarizing layer is improved substantially. The light polarizing article has improved chemical, mechanical and thermal resistance. The light polarizing article can be used, for example, as ophthalmic products and in display devices.
