Synthesis and investigation of chemically modified silicas with the island structure of the grafted layer.
Publication date: 2000
Journal: Kinetics And Catalysis
Abstract: Island structures on the chemically modified surface of silica are synthesized by the method of matrix prints. Dichlorosilicon phthalocyanine and copper naphthalocyanine were used as molecular templates. Two types of heterogeneous surfaces are prepared by this method: the islands of nonmodified silica on the tri-methylsilylated silica (the first type) and the islands of aminopropyl silica on the esteric groups grafted on silica (the second type). The structure of the surfaces prepared is studied by ESR spectroscopy with the use of para-magnetic probes
