Abstract
Provided herein are compositions and methods for use of an organosilica material comprising a copolymer of at least one monomer of Formula [RRSiCH](I), wherein, Rrepresents a C-Calkoxy group; and Ris a C-Calkoxy group or a C-Calkyl group; and at least one other monomer of Formula [(ZO)ZSi—Z—SZ] (II), wherein, Zrepresents a hydrolysable functional group; Zrepresents a C-Calkyl or aryl group; Zrepresents a C-Ccyclic or linear hydrocarbon; Zis either H or OH; and x represents any one of integers 1, 2, and 3. The composition may be used as a support material to covalently attach transition metal cations, as a sorbent for olefin/paraffin separations, as a catalyst support for hydrogenation reactions, as a precursor for highly dispersed metal nanoparticles, or as a polar sorbent for crude feeds.
