Hybrid thiol–ene network nanocomposites based on multi(meth)acrylate POSS

Cinnamate‐Functionalized Cage Silsesquioxanes as Photoreactive Nanobuilding Blocks

“…Previous studies have found that cage rearrangement occurs during the nucleophilic substitution of SQs_Cl 8 , and the cage-rearranged products (T 10 and T 12 , Scheme 1) form instead of T 8 . [19][20][21][22] Although cage rearrangement results in mixtures, it provides a practicable route to other cage compounds, which are usually difficult to synthesize. [23,24] The resulting product was subjected to 29 Si NMR spectroscopy, and we observed several peaks ( Figure 1).…”

“…This could be attributed to the formation of quite stable networks through the self-polymerization of OpcSQs and DpcSQs during the heating process. [22] TGA was also performed in air at a heating rate of 10°C/min. The ceramic yields of these cage compounds obtained from the TGA were closer to the theoretical values.…”

Silsesquioxane-based luminescent PMMA nanocomposites

“…[13][14][15] Multimethacrylate substituted cages have been synthesized by different methods, such as hydrosilylation, 16 nucleophilic substitution 17 and hydrolytic condensation, 18 and some hybrid nanocomposites have been prepared from these cage monomers via thermal polymerization [19][20][21][22] or photopolymerization. 23,24 However, these cage compounds have not been used as a ligand to coordinate with rare earth ion to form a hybrid complex containing polymerizable methacrylate group. This hybrid complex is very promising to provide better thermal stability and mechanical strength for the preparation of hybrid luminescent nanocomposites and extends the application of methacrylate functionalized cage silsesquioxanes.…”

An orthogonal, one-pot, simultaneous UV-mediated route to thiol-ene/sol-gel film

“…However, most of the reported synthesis methodologies remain sequential describing a thiol-ene step uncoupled from the sol-gel process [9]. In most instances, the (photoinduced) thiol-ene cross-linking was thus carried out subsequently from isolated and purified thiol-or vinyl-functionalized hybrid building blocks including silsesquioxanes [10][11][12][13][14][15][16][17], POSS (polyoligomeric silsesquiox-ane) cages [18,19] or zirconium oxoclusters [20], all prepared separately. These approaches were derived from the conventional two-step route used to synthesize hybrid sol-gel photopolymer films via radical or cationic photopolymerization [21].…”
