In this paper, the effective functionalization of silsesquioxane (HSiMe 2 O) 8 Si 8 O 12 (1) via hydrosilylation of two different functional alkenes is presented. For the first time, such a wide spectrum of statistically bifunctional silsesquioxanes (RSiMe 2 O) ∼4 (R′SiMe 2 O) ∼4 Si 8 O 12 was obtained and characterized. Seventeen new systems with various substituents (Si−H, hydroxyl, ester, epoxy, alkenyl, or alkyl) were prepared by two synthetic approaches. The first method was based on the subsequent hydrosilylation of two alkenes in a one-pot manner, whereas the second one consisted of a twos t e p p r o t o c o l i n w h i c h i n t e r m e d i a t e s ( R S i -Me 2 O) ∼4 (HSiMe 2 O) ∼4 Si 8 O 12 were isolated and then reacted with the second alkene, in the presence of the same or a different catalyst. Resulting systems due to the presence of two various groups attached to the silsesquioxane cage can be considered as potential cores for the synthesis of (hyper)branched molecules or macromolecules.

“…As an effective method in creating three-dimensional nanostructures by assembling a two-dimensional molecular layer at the air–water interface, the Langmuir–Blodgett (LB) technique is considered to be the most widely utilized one [ 133 , 134 ]. In the past few years, POSS-based materials have been recognized as promising materials forming stable Langmuir films [ 135 , 136 , 137 , 138 ]. For example, Ishizaki and coworkers prepared a porous SiO 2 nanofilm by using hybrid block copolymers consisting of N-dodecyl acrylamide (DDA) and silsesquioxane (SQ) comonomers (p(DDA/SQ26)- b -pDDA) ( Figure 17 ) [ 77 ].…”

Self-Assembly and Applications of Amphiphilic Hybrid POSS Copolymers

et al. 2018

View full text Add to dashboard Cite

Understanding the mechanism of molecular self-assembly to form well-organized nanostructures is essential in the field of supramolecular chemistry. Particularly, amphiphilic copolymers incorporated with polyhedral oligomeric silsesquioxanes (POSSs) have been one of the most promising materials in material science, engineering, and biomedical fields. In this review, new ideas and research works which have been carried out over the last several years in this relatively new area with a main focus on their mechanism in self-assembly and applications are discussed. In addition, insights into the unique role of POSSs in synthesis, microphase separation, and confined size were encompassed. Finally, perspectives and challenges related to the further advancement of POSS-based amphiphilics are discussed, followed by the proposed design considerations to address the challenges that we may face in the future.

“…On the other hand, adopting oapPOSS for surface modication of GO can lead to the enhanced hydrophobicity because the POSS derivatives was reported to be the effective hydrophobic agents. 39,40 This is also possibly benecial to the improvement in the compatibility and hence the mechanical performance of FR PP composite from another point of view.…”
