An inorganic-organic hybrid fluorescence chemosensor (R6G-SBA-15) was prepared by covalent immobilization of a Rhodamine 6G derivative within the channels of mesoporous silica material SBA-15 via triethoxysilane groups. The primary hexagonally ordered mesoporous structure of SBA-15 is preserved after the grafting procedure. R6G-SBA-15 features effectively(More)
Carbon nanotubes (CNTs) were covalently modified by fluorescence ligand (glycine-N-8-quinolyla-mide) and formed a hybrid material which could be used as a selective probe for metal ions detection. The anchoring to the surface of the CNTs was carried out by the reaction between the precursor and the carboxyl groups available on the surface of the support.(More)
Novel covalent porphyrin and its complexes (Co 2? , Zn 2?) functionalized multi-walled carbon nano-tubes (MWNTs) have been successfully synthesized by the reaction of the carboxyl on the surface of MWNTs which was synthesized to use carbon radicals generated by the thermal decomposition of azodiisobutyronitrile (AIBN) with(More)
