The Role of POSS Functionality on Induced Deviation of Nano and Micromechanical Properties of UV Curable Urethane Acrylate Nanocomposite Coatings

Exploring Polyol-Functionalized Dendrimers with Silsesquioxane Cores

“…SQs are a family of structures, which could be divided into random resins or defined architectures, i.e., ladder, open- and closed-cage silsesquioxanes and double-decker silsesquioxanes (DDSQ). − The multiplicity of structures and the presence of various reactive groups, e.g., Si–OH, Si–H, Si–HCCH 2 , enable their modification by stoichiometric (condensation, nucleophilic substitution) and catalytic reactions (hydrosilylation, metathesis, Heck or Sonogashira coupling, O -silylation) . As a result, diverse silsesquioxane-based functionalized systems are obtained that may exhibit interesting physicochemical properties that affect their possible application, resulting in the use of, i.e., materials chemistry, OLEDs, catalysis, or medicine. − Within the great variety of functional groups, the SQs possessing hydroxyl-terminated aliphatic substituents may be of special concern. − There are numerous scientific reports on the use of diol derivatives of SQs as comonomers of polyesters or polyurethanes − and also in the chemistry of biomedical materials . In addition, they have been reported in materials to remove dyes from wastewater or Ag­(I) ions from aqueous solutions. , …”

Acetone Factor in the Design of Cu4-, Cu6-, and Cu9-Based Cage Coppersilsesquioxanes: Synthesis, Structural Features, and Catalytic Functionalization of Alkanes

“…The investigation of partly condensed POSS is also appealing, leading to the design of new monomers for copolymerization reactions, H-bond donor catalysts, OLED’s emission layers, three-dimensional emulsifiers, different films (e.g., transparent, scratch resistant, self-healing, or Langmuir–Blodgett/Langmuir–Schaefer films), and spin-on-glass networks with ultralow dielectric constants . By design, partly condensed polyhedral silsesquioxanes can be also regarded as versatile ligands for the construction of various cagelike metallacomplexes. − These intriguing compounds attract significant interest for the potential removal of radioactive elements, fabrication of flame retardants, − biomedical agents, luminescent materials, , or molecular magnets .…”

“…Among many fascinating and functional structures, available via the first approach, we can mention polyhedral oligomeric silsesquioxanes (POSS) bearing chromophore groups, 6,7 materials for sorption of heavy-metal ions/ dyes/organic solvents from water, 8−11 additives for polymers, 12 components of nanoscale building blocks, 13,14 shape amphiphiles, 15 organocatalysts, 16 building blocks for the construction of magnetic materials, 17 and luminescent devices or lightharvesting systems. 18,19 The investigation of partly condensed POSS is also appealing, 20 leading to the design of new monomers for copolymerization reactions, 21 H-bond donor catalysts, 22 OLED's emission layers, 23 three-dimensional emulsifiers, 24 different films (e.g., transparent, 25 scratch resistant, 26 selfhealing, 27 or Langmuir−Blodgett/Langmuir−Schaefer films 28 ), and spin-on-glass networks with ultralow dielectric constants. 29 By design, partly condensed polyhedral silsesquioxanes can be also regarded as versatile ligands for the construction of various cagelike metallacomplexes.…”

Thermal and morphological investigation of the effect of POSS‐(PEG2000)8 addition to UV curable PEGMEA/PEGDA formulation and simultaneously in situ formed silver nanoparticles

“…Polyhedral oligomeric silsesquioxane (POSS), referred to as molecular silica, is one of the ideal candidates in this regard. [2] Unlike other inorganic materials, POSS has excellent compatibility with a matrix. [3][4][5][6] A lot of work has been done on the organic groups (R) in each of the eight corners of the POSS to produce hybrid polymers with a wide variety of properties.…”
