Abstract

Amino functionalized multi wall carbon nanotubes (MWNT) were reacted with an inorganic Ruthenium complex, {[Ru(dcclbpy)(bpy)₂](PF₆)₂}, in an attempt to covalently attach the Ruthenium complex to the MWNT. The covalent attachment between the Ruthenium complex and the carbon nanotubes is achieved by the formation of an amide group. Absorption and emission spectroscopy indicated that a reaction between the amino functionalized MWNT and the Ruthenium complex occurred. Atomic fore microscopy (AFM) images gave further evidence of a successful attachment of the Ruthenium complex to MWNT by showing multiple junctions between MWNT distinct from naturally occurring splitting of MWNT ropes.
