    • note
    • Repeated filtration, washing, and resuspension of the polymer-nanotube complex resulted in the removal of some free polymer from solution at each iteration (as evidenced by some brown color in the filtrate) and consequent sedimentation of a small quantity of nanotubes after centrifugation. However, repetition of this process in excess of ten times still yielded a significant amount of soluble nanotube material, even though free polymer is removed at each iteration. This signifies an equilibrium between nanotube-bound and free polymer that is re-established at each resuspension step.

    • note
    • It was found that the Zn-porphyrin polymer remained extremely stable to TEA in THF, with no observable demetalation. However, in noncoordinating solvents, such as dichloromethane, demetalation of polymer 2 occurs at elevated temperatures in the presence of TEA. Conversely, monomer 1 is more easily demetalated by TFA, with complete demetalation occurring within minutes in dichloromethane, and several days in THE at room temperature. The reason for this stability difference between the monomer and the polymer is currently unclear.
