“…X. Su and coworkers reported the synthesis of POSS modified with azobenzene, acetylene or stilbene derivatives exhibiting nonlinear absorption. [363][364][365] These systems exhibited large P (3) susceptibility and efficient reverse saturable absorption with enhanced thermal stability. They were processed as thin films.…”

Research on hybrid inorganic‐organic materials has experienced an explosive growth since the 1980s, with the expansion of soft inorganic chemistry based processes. Indeed, mild synthetic conditions, low processing temperatures provided by “chimie douce” and the versatility of the colloidal state allow for the mixing of the organic and inorganic components at the nanometer scale in virtually any ratio to produce the so called hybrid materials. Today a high degree of control over both composition and nanostructure of these hybrids can be achieved allowing tunable structure‐property relationships. This, in turn, makes it possible to tailor and fine‐tune many properties (mechanical, optical, electronic, thermal, chemical…) in very broad ranges, and to design specific multifunctional systems for applications. In particular, the field of “Hybrid‐Optics” has been very productive not only scientifically but also in terms of applications. Indeed, numerous optical devices based on hybrids are already in, or very close, to the market. This review describes most of the recent advances performed in this field. Emphasis will be given to luminescent, photochromic, NLO and plasmonic properties. As an outlook we show that the controlled coupling between plasmonics and luminescence is opening a land of opportunities in the field of “Hybrid‐Optics”.

“…Further examples of the use of silsesquioxane derivatives in hydrosilylation with azo-chromophores in order to form functionalizable POSS nanoparticles have been reported by the Xu, Tsukruk and Miniewicz groups independently [105,106,107,108,109]. The procedures, allowing the synthesis of POSS derivatives with azobenzene mesogenes, have been proposed via the hydrosilylation of respective octahydro-substituted T 8 silsesquioxanes.…”

“…Xu presented a group of azobenzene-containing POSS-based star-like hybrid functional materials obtained via hydrosilylation octahydridosilsesquioxane with three different azobenzene chromophores containing terminal alkynyl moiety as the reactive fragments [109]. The reactions were carried out in the presence of platinum dicyclopentadiene complex [Pt(dcp)] at 80 °C, using an eight-fold molar excess of olefin relative to silsesquioxane.…”

Over the past two decades, organic optoelectronic materials have been considered very promising. The attractiveness of this group of compounds, regardless of their undisputable application potential, lies in the possibility of their use in the construction of organic–inorganic hybrid materials. This class of frameworks also considers nanostructural polyhedral oligomeric silsesquioxanes (POSSs) with “organic coronae” and precisely defined organic architectures between dispersed rigid silica cores. A significant number of papers on the design and development of POSS-based organic optoelectronic as well as photoluminescent (PL) materials have been published recently. In view of the scientific literature abounding with numerous examples of their application (i.e., as OLEDs), the aim of this review is to present efficient synthetic pathways leading to the formation of nanocomposite materials based on silsesquioxane systems that contain organic chromophores of complex nature. A summary of stoichiometric and predominantly catalytic methods for these silsesquioxane-based systems to be applied in the construction of photoactive materials or their precursors is given.

“…As a result, the incorporation of POSS has led to enhancement in the physical properties of materials such as thermal and mechanical stability, flammability, oxidative resistance, and low dielectric constant . Thus POSS‐based hybrids have been widely studied in many areas of potential use, such as luminescence emission, nonlinear optics, resist coatings for lithography, laser protection, integrated circuits industry as low dielectric constant materials, and so on …”

Three kinds of hybrids with different architectures including dumbbell-type, bead-type, and cross-linked structure, were prepared via the Heck reaction between octavinyl-polyhedral oligomeric silsesquioxane (OV-POSS) and different bromo-substituted aromatic amide monomers. The molecular architecture can be successfully achieved by simply varying the feed ratio of OV-POSS to monomers. Their structure and properties were characterized by FTIR, 1 H NMR, 29 Si NMR, provide the expansion for FTIR and NMR] All the POSS-based hybrids exhibited good thermal stability and low dielectric constant properties. The relationship between chemical structure, molecular architecture, and the dielectric constant of these hybrids were investigated in detail. The results show that POSS content dominated the low dielectric constant of the hybrids, while the chemical structure of organic chains and molecular architecture also play an important role on the formation of low dielectric constant.
