    • It has previously been shown using functionalized alkoxyamines and a crossover strategy that efficient exchange of the persistent nitroxide radicals occurs very early in the polymerization. C. J. Hawker, G. G. Barclay, J. Dao, J. Am. Chem. Soc. 1996, 118, 11467.

    • A 1 : 24 molar ratio of the dodeca-initiator (18) to the pyrene-labelled initiator (19) was employed. In terms of the ratio of alkoxyamine groups, this represents a 1 : 2 ratio of alkoxyamine groups for (18) (12 alkoxyamine groups per molecule) compared with (19) (1 alkoxyamine group per molecule.)

    • note
    • While coupling of two or more linear chains to the star polymer leading to a multiply-functionalized star is statistically possible, the low occurrence of monofunctionalization makes the incorporation of two or more pyrene functionalities unlikely. Therefore, in the calculation of the relative percentage of pyrene functionalized star polymers only mono-addition was considered. Additionally, intramolecular termination between arms within the star polymer is not considered.
