摘要:The invention is directed to small molecules that self-assemble hierarchically to form NPs termed SHS (due to their architectural features). These SHS are composed by precise supramolecules known as Supramolecular G-Quadruplexes (SGQs) which are formed when amphiphilic guanosine (G) derivatives that self-assemble in presence of salt by non-covalent interactions. The resulting SGQs are made of amphiphilic guanosine (G) subunits (with precisely eight subunits at neutral pH (pH>5.7) or sixteen subunits at acidic pH (pH<5.7)). The SGQs are responsive entities that further self-assemble upon an external stimulus, such as an increase in temperature or a change in pH, leading to the formation of the aforementioned SHS.

摘要:A carbamate-functional alkoxysilalkylenesilane compound and methods for its preparation and use are provided. The compound has formula (R 1 2 )N—C(â•?O)O—Si(R 2 2 )-D-Si(OR 4 ) 3 , where R 1 may be hydrogen, methyl, or ethyl; R 2 may be methyl, R 4 may be methyl, and each instance of D is a linear or branched alkylene group such as —CH 2 —CH 2 — and —CH(CH 3 )—. The compound may be used to cap silanol moieties in a silanol-functional polyorganosiloxane to produce a polyalkoxy-functional polyorganosiloxane. The polyalkoxy-functional polyorganosiloxane may be used as a crosslinker in a moisture curable room temperature vulcanizing (RTV) silicone composition.
