  • Publication number: 20050200803
    Abstract: The present invention is phthalocyanine compounds with peripheral siloxane substitution, as well as methods for making these compounds and various uses thereof, having the basic structure: wherein —W—X—Y-Z are peripheral groups comprising individual W, X, Y, and Z subgroups; W is a linkage represented by the formula: -D-(R1)0.1-, where D=S or O; X is: —(CH2)n—, n=2 to 8; Y is a siloxane chain; Z is an aryl or alkyl terminal cap; M is two protons or a metal ion; and forms a transparent film of high optical quality with large nonlinear absorption and thermal refraction, free of scattering from solid or liquid crystalline domains making them highly suitable for use as the active component in thin films protective eye wear, and optical data storage applications.

  • Publication number: 20050084666
    Abstract: The invention provides an optical filter comprising: a. an organic, solar blind filter dye; and b. a UV-transparent, non-scattering and chemically stable substrate. The substrate may be a UV-transparent nanoporous silica glass solid having pores that are substantially filled with a UV-transparent solvent, which has been selected to dissolve said dye and also to match the refractive index of the nanoporous silica glass solid. Alternatively, the substrate may be a UV-transparent inorganic salt compressed to form a solid body. The invention also provides for methods of making these embodiments and an optical device comprising such an optical filter. The filter provides an efficient solar blind filter that is chemically and dimensionally stable.
