25. By converging we mean that the triazines are inwardly directed toward the center, not convergent. Similarly for diverging and divergent, except outwardly directed.

39. This precipitation effect has been observed previously for a cobaltocene-based dendrimer/cyclodextrin system. González, B.; Casado, C. M.; Alonso, B.; Cuadrado, I.; Morán, M.; Wang, Y.; Kaifer, A. Chem. Commun. 1998, 2569-2570.
40. At the concentrations used for these electrochemical studies, approximately 25% of guest 2 is encapsulated, based on expected association constants. As shown by the electrochemical experiments, this 25% reduction in free guest 2 is sufficient to prevent aggregation and concomitant precipitation.
41. In addition to preventing aggregation of oxidized target 2, addition of polymer 1 caused a dramatic decrease in peak current, and an increase in peak-to-peak for guest 2. This is a well-established behavioral pattern for encapsulated redox centers, resulting from inefficient electron transfer due to physical separation of the electroactive species from the electrode surface.
