Fluorinated Silsesquioxanes

This perspective will highlight the significant advances in the field of fluorinated organically modified silicas occurring since 2014. After a brief introduction, an overview of the synthetic methods employed for obtaining these organic–inorganic hybrid materials with an emphasis on the lesser utilized and new synthetic methods will be given. Furthermore, novel applications beyond the more traditional non‐wetting coatings and surfaces will also be featured. © 2015 Society of Chemical Industry

“…Nearly 20 years later, Brown and Vogt (1965) published on the first partially condensed POSS compounds and proposed the first ladderlike POSS materials (Brown 1965). Since then, the field has continued to mature and these hybrid organic-inorganic molecular frameworks have found applications in catalysis (Abbenhuis 2000), biomaterials (Ghanbari et al 2011), optics (Hartmann-Thompson 2011), and coatings (Ramirez and Mabry 2014). There are a number of noteworthy reviews that have been published on the preparation and applications of POSS (Lickiss and Rataboul 2008;Cordes et al 2010).…”

This chapter aims to highlight the selected applications of polyhedral oligomeric silsesquioxanes (POSS). A brief introduction will be given and used to highlight the use of solution-gelation chemistry for the synthesis of POSS. Furthermore, the different three-dimensional structures, including fully and incompletely condensed, random, and ladder structures, will be discussed. Subsequently, the use of the various POSS structures as fillers in polymeric nanocomposites will be examined, with a focus on polymer blends, pendant polymers, bead polymers,

“…14 When the silica-gel monomer contains a trivalent reaction site, such as an alkyltrichlorosilane, they can under certain conditions selfassemble into nanobead structures during polymerization. 15 In this work, we describe a high-performing perfluoroalkyl silsesquioxane 16 coating for SALDI-MS. Our approach, called insulator nanostructure desorption ionization mass spectrometry (INDI-MS) to differentiate this polymer-based approach from existing metal/semiconductor SALDI surfaces, utilizes the low-cost and simplicity of organic electronics fabrication to generate NIMS-like SALDI surfaces. To gain insights into the surfaces, we compare materials and find that the trichlorosilane and perfluorous moieties to be important components.…”

Surface-assisted laser desorption ionization (SALDI) is an approach for gas-phase ion generation for mass spectrometry using laser excitation on typically conductive or semiconductive nanostructures. Here, we introduce insulator nanostructure desorption ionization mass spectrometry (INDI-MS), a nanostructured polymer substrate for SALDI-MS analysis of small molecules and peptides. INDI-MS surfaces are produced through the self-assembly of a perfluoroalkyl silsesquioxane nanostructures in a single chemical vapor deposition silanization-step. We find that surfaces formed from the perfluorooctyltrichlorosilane monomer assemble semielliptical features with a 10 nm height, diameters between 10 and 50 nm, and have attomole-femtomole sensitivities for selected analytes. Surfaces prepared with silanes that either lack the trichloro or perfluoro groups, lack sensitivity. Further, we demonstrate that hydrophobic INDI regions can be micropatterned onto hydrophilic surfaces to perform on-chip self-desalting in an array format.
