Fig. 8. Rate constants for radical formation as a function of pH for 2MP-α3C (orange dots) and 4MP-α3C (green triangles), with [Ru(deeb)3]3+ as oxidant, and α3Y (black circles, fit with a purple dotted line curve) with [Ru(bpy)3]3+ as oxidant from ref. 13, other conditions as in Fig. 7. Standard deviations are shown, but are often smaller than the size of the data symbols. Fits according to eqn (1) are shown (see Table 4 for results).
