Carbofunctional sulfur‐containing organosilicon compounds

“…First of all are the organosilicon sulfides and polysulfides, which appear to be effective coupling agents, additives for vulcanizing high‐quality materials and compositions for car tires, that are easy moldable and stable for rubbing, etc . Newly designed carbofunctional sulfur‐containing organosilicon monomers and polymers have made a great contribution to the development of the field of chemistry of organosilicon compounds as ion‐exchanging and complexing sorbents, and they open an entirely new page on organosilicon chemistry that are new materials having metallochromic properties. The latter have potential for the new generation of test systems.…”

“…Reactions of poly[bis‐ N , N ‐(silsesquioxanylalkyl)‐ S , S ‐dioxathiocarbamide] with ammonia or with methylamine, which were carried out to obtain organosilicon polymers bearing carbofunctional guanidine or methylguanidine groups, were attributed to relatively rare substitution reactions of replacing one carbofunctional substituent for another in the silsesquioxane polymer matrix without decomposition of the matrix structure . The reaction was exothermic and performed during 10 min (Scheme ).…”

Ethylene and phenylene bridged polysilsesquioxanes functionalized by amine and thiol groups as adsorbents of volatile organic compounds

“…Despite that there are only a few papers in the literature describing the potential use of polysilsesquioxane adsorbents. They were extensively probed as adsorbents of different metal from aqueous solutions [9][10][11][12], phenols [13] or DDT [14] but to our best knowledge there have been no attempts to probe these materials as adsorbent of organic compounds from the gas phase. Here, we describe a synthesis of mesoporous polysilsesquioxane xerogels and their application as sorbent materials for the uptake of selected organic compounds from the gas phase.…”
