    摘要: The present invention relates to a process for the preparation of organic-inorganic hybrid silicates and metal-silicates of the ECS type which uses as starting material the corresponding disilanes: said process is characterized by the presence of boric acid in the reagent mixture. With the process of the invention, ECS silicates and metal-silicates are obtained, characterized by an X-Ray diffractogram with reflections exclusively at angular values higher than 4.0° of 2Θ, and characterized by an ordered structure which contains: —structural units having formula (a), wherein R is an organic group: —boron—one or more elements T, different from boron, selected from groups IIIB, NB, VB, and transition metals, with a molar ratio Si/(Si+T) in said structure greater than 0.3 and lower than 1, wherein Si is the silicon contained in the structural unit having formula (a). The silicates and metal-silicates so obtained, containing both boron and at least one element T, are new. The process also allows new crystalline phases called ECS-13 and ECS-14 to be prepared.

    摘要: There is a diaryloxybenzoheterodiazole compound di-substituted with thienothiophenic groups having general formula (Ia): The diaryloxybenzoheterodiazole compound di-substituted with thienothiophenic groups having general formula (Ia) can be advantageously used as a spectrum converter in luminescent solar concentrators (LSCS) capable, in turn, of improving the performance of photovoltaic devices (or solar devices), selected for example, between photovoltaic cells (or solar cells), photovoltaic modules (or solar modules), either on a rigid support, or on a flexible support. More particularly, said photovoltaic devices (or solar devices) can be advantageously used in the construction of greenhouses.
