    Abstract: A composition having a polysulfide polysilane formed by the reaction of a polythiol and an alkenyl silane. The reactants are combined in a thiol-ene addition process driven by UV radiation or heat, preferably by UV radiation. The polysulfide polysilane is then hydrolyzed and may be combined with other hydrolyzed compounds. For coatings, the polysulfide polysilane is hydrolyzed and may optionally be combined with nanoparticles. For bulk materials, the polysulfide polysilane is hydrolyzed, concentrated and heated to form a high refractive index material which can be used to form lenses.

    Abstract: The invention relates to a method of producing a substrate which is coated with a mesoporous layer and to the use thereof in ophthalmic optics. The inventive method comprises the following steps comprising: preparing a precursor sol containing (i) a precursor agent that is selected from compounds having formula M(X)4 (I), in which X is a hydrolysable group and M represents silicon or a tetravalent metal and mixtures thereof, (ii) at least one organic solvent, (iii) at least one pore-forming agent and (iv) water; depositing a film of the precursor sol on a main surface of the substrate; optionally consolidating the mesoporous structure of the deposited film; eliminating the pore-forming agent; and recovering the substrate coated with the mesoporous layer. The method is characterized in that: (i) the pore-forming agent is eliminated at a temperature of less than or equal to 150° C.; and (ii) the method comprises a step involving the introduction of at least one reactive agent bearing at least one hydrophobic group, before the deposition step and/or after said step.

    Abstract: The present invention relates to an article comprising a substrate having a main surface coated with a coating, part of which at least is mesoporous and has a refractive index profile with optical function, whose variation is imposed by the mesopore content and/or the filling ratio of the mesopores. The profile may be such that the refractive index varies depending on the distance to a given axis, or such that the refractive index variation is monotone, decreasing along any axis which is perpendicular to the surface of the substrate underlying the mesoporous part of said coating and oriented away from the substrate. The present invention also relates to methods for making said article, which differ depending on the technique from which the refractive index profile is created. The invention is applicable to ophthalmic optics.
