    • Dendrimers are thought to undergo a change from an extended structure to a globular structure between the third and fourth generations. For example, see: Hawker, C. J.; Wooley, K. L.; Fréchet, J. M. J. J. Am. Chem. Soc. 1993, 115, 4375.

    • Since this was a rather surprising result for us, we repeated the TMEDA and DABCO experiments with dendrimers 7 and 8 several times. The values obtained were within the 5% experimental error.

    • We ran MM2-based energy minimizations on DABCO and TMEDA. We got several low-energy conformations for TMEDA in which the N1-N2 through-space distance ranged from 2.8 to 3.8 Å. However, with DABCO, this distance was always 2.6 Å in as many iterations. See also: Wong, N. B.; Cheung, Y. S.; Wu, D. Y.; Ren, Y.; Tian, A.; Li W. K. J. Phys. Chem. A 2000, 104, 6077.
