Novel adamantane-based periodic mesoporous organosilica film with ultralow dielectric constant and high mechanical strength

Insight into the Molecular Self-Assembly and Structural Organization of Mesoporous Hybrid Silica Films with Binary Composition

“…In this process, solvent evaporation from the initial sol triggers the simultaneous condensation of the inorganic network and arrangement of surfactant molecules into a well-defined array. , If organoalkoxysilanes are used as a silica source, a permanent introduction of the functional groups into the film’s structure is possible thanks to co-condensation . Such materials combine the aforementioned advantages (i.e., superior specific surface area, organized, high porosity, and easy-tailored surface chemistry), which makes it valuable for drug delivery, sensors, − pollutant adsorption, − low-k, , and functional coatings, , or bioactive applications. , In addition to this one-pot approach, two other routes of functionalization exist: postgrafting and the usage of mono- and bis-silylated organic precursors . However, only the co-condensation provides homogeneous distribution within the matrix. , …”
