摘要: A novel full-conjugated 4-(2,2′:6′,2′′-terpyrid-4′-yl) benzenediazonium tetrafluoroborate (diazo-tpy) was synthesized and used for surface modification of materials, such as quartz wafers, ITO glass, silicon, multiwalled carbon nanotubes (MWCNTs). Under UV irradiation, the diazonium group diazo-tpy is decomposed residual terpyridine covalently anchored to substrates. The obtained tpy-modified MWCNTs (tpy-MWCNTs) have good solubility in common organic solvents. TGA HRTEM analyses confirmed that groups been symmetrically grafted on MWCNTs. thickness monolayer about 2.3 nm, which approximately 2 times axial length 4-(2,2′:6′,2′′-terpyrid-4′-yl)phenyl group. introduction provides a coordination site complex with metal ions. Multilayer films were fabricated from tpy-MWCNTs ruthenium ions [Ru(III)] via layer-by-layer self-assembled (LBL SA) technique ...
