Abstract: Provided herein are compositions and methods for use of an organosilica material comprising a copolymer of at least one monomer of Formula [R1R2SiCH2]3 (I), wherein, R1 represents a C1-C4 alkoxy group; and R2 is a C1-C4 alkoxy group or a C1-C4 alkyl group; and at least one other monomer of Formula [(Z1O)xZ23-xSi—Z3—SZ4] (II), wherein, Z1 represents a hydrolysable functional group; Z2 represents a C1-C10 alkyl or aryl group; Z3 represents a C2-C11 cyclic or linear hydrocarbon; Z4 is either H or O3H; 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.
