چکیده
The closely related title compounds, 3-(2,5-dimeth-oxy-3,4,6-tri-methyl-phen-yl)propyl methacrylate, C18H26O4 (I), and 3-(2,4,5-trimethyl-3,6-dioxo-cyclo-hexa-1,4-dien-yl)propyl methacrylate, C16H20O4 (II), are monomers suitable for the preparation of redox polymers. They consist of a propyl-methacrylate group and three methyl substituents on di-meth-oxy-benzene and quinone cores, respectively. Both crystal structures feature weak C-H⋯O hydrogen bonds and C-H⋯π(ring) contacts between methyl groups and the six-membered rings.

Crystal structure of 7-phenyl-7-(2,4,5-trimethyl-3,6-dioxocyclohexa-1,4-dien-1-yl)heptanoate 1,3-dihydroxy-2-(hydroxymethyl)propan-2-aminium monohydrate: a new solid form of seratrodast
In the title hydrated salt, C4H12NO3 (+)·C22H25O4 (-)·H2O, seratrodast [systematic name: 7-phenyl-7-(2,4,5-trimethyl-3,6-dioxo-cyclo-hexa-1,4-dien-1-yl)hepta-noic acid] crystallized with trometamol [systematic name: 2-amino-2-(hydroxyméth-yl)propane-1,3-diol] to form a monohydrated salt form of seratrodast. The carb-oxy-lic acid group of seratrodast has transferred its proton to the amino N ato...
متن کاملPreparation and characterization of alkyl methacrylate-based monolithic columns for capillary gas chromatography applications.
Gas chromatography (GC) is considered the least common application of both polymer and silica-based monolithic columns. This study describes the fabrication of alkyl methacrylate monolithic materials for use as stationary phases in capillary gas chromatography. Following the deactivation of the capillary surface with 3-(trimethoxysilyl)propyl methacrylate (TMSM), the monoliths were formed by th...
متن کاملToward Hybrid Materials: Group Transfer Polymerization of 3-(Trimethoxysilyl)propyl Methacrylate.
In this study, the group transfer polymerization (GTP) of the functional monomer 3-(trimethoxysilyl)propyl methacrylate (TMSPMA) is reported to produce polymers of different architectures and topologies. TMSPMA is successfully polymerized and copolymerized with GTP to produce well-defined (co)polymers that can be used to fabricate functional hybrid materials like hydrogels and films.
متن کاملThe preparation of Ni-plated polystyrene microspheres using 3-(trimethoxysilyl) propyl methacrylate as a bridging agent
This study focuses on the preparation of Ni-plated polystyrene (PS) microspheres (diameter 3.7–4.5 μm). These Ni-plated PS microspheres have core–shell structures that were designed and prepared using an organic polymer core (PS with 3-(trimethoxysilyl) propyl methacrylate (TSPM)) and an inorganic metal (Ni) plated shell. The polymer microspheres were synthesized by dispersion copolymerization,...
