摘要: The outer surface of multi-walled carbon nanotubes (MWCNTs) was successfully modified with 7-bromo-9,9-dioctylfluorene-2-carbaldehyde by using 1,3-dipolar cycloaddition azomethine reaction to introduce bromo functional groups. peripheral groups can be used further react AB-type monomers through Suzuki polycondensation afford the PF-functionalized MWCNTs, which are a cable-like structure. Through covalent connection fluorescence polyfluorenes completely quenched indicating fast photo-induced electron transfer from MWCNTs.
