“…All the hybrid materials displayed the characteristic stretching vibration absorption band of SieOeSi at~1123 cm À1 , indicating the incorporation of POSS into the organic dyes. To introduce the dyes with different absorption bands to the hybrids, in the synthesis of PA, the molar ratio of 9-bromoanthracene to OV-POSS was 2, thus there were large amount of vinyl groups left in PA, which was confirmed by the absorption band at 1602 cm À1 , originated from the stretching vibration of CH]CH 2 [31]. The absorption bands between 3059 and 2958 cm À1 were attributed to the stretching vibration of ]CeH in both CH]CH 2 and anthracene.…”

“…Xu et al presented a Heck coupling-based strategy to obtain anthracene-substituted T 8 cage via a [Pd(OAc) 2 ]/PPh 3 -catalyzed reaction at room temperature in various reagent stoichiometry resulting in differently substituted products (Figure 8) [48]. The substitution was also statistical, but with the majority of the presented forms of products that depended on the possibility to form a complex between palladium with bromoanthracene substrate.…”

Synthetic Routes to Silsesquioxane-Based Systems as Photoactive Materials and Their Precursors

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.

“…Nevertheless, hydrosilylation remains one of the most useful methods for obtaining bifunctional silsesquioxanes, and it has been the subject of multiple research papers [ 7 , 8 , 10 , 12 ]. Heck coupling [ 28 , 29 , 30 , 31 ] and condensation reactions [ 32 , 33 , 34 , 35 , 36 ] were also applied in this type of synthesis. There are also single notes on the utilization of thiol-ene [ 37 ], hydration [ 38 , 39 ] and click type reactions [ 40 , 41 , 42 ] for the synthesis of multifunctionalized silsesquioxanes.…”

Bifunctional silsesquioxanes create an attractive group of compounds with a wide range of potential applications, and recently they have gained much interest. They are known to be obtained mainly via hydrosilylation, but we disclose novel synthetic protocols based on different but complementary reactions, i.e., cross-metathesis (CM) and silylative coupling (SC). A series of cubic T8 type silsesquioxane derivatives with a broad scope of styryl substituents were synthesized in a one-pot procedure and characterized by spectroscopic and spectrometric methods. All of the new compounds can be obtained in a one-pot manner, which has an attractive impact on the synthetic procedure, as it is economic in terms of the isolation of intermediate products. Additionally, the methodology disclosed here enables the (E)-stereoselective introduction of styrenes derivative to the cubic T8 type core. The presented compounds can be interesting precursors for a further functionalization that may significantly increase the possibility of their application in the design and synthesis of new functional materials.
