Organized thiol functional groups in mesoporous core shell colloids

摘要: Abstract The co-condensation in situ of tetraethoxysilane (TEOS) and mercaptopropyltrimethoxysilane (MPTMS) using cetyltrimethylammonium bromide (CTAB) as a template results the synthesis multilayered mesoporous structured SiO2 colloids with “onion-like” chemical environments. Thiol groups were anchored to an inner selected porous layer bilayered core shell particle producing different regions inside colloidal layered structure. X-Ray Photoelectron Spectroscopy (XPS) shows preferential anchoring –SH double system, while porosimetry simple modifications confirm that pores are accessible. We can envision interesting objects defined environments highly controlled properties.
