Figure 7

(a) Plot of the change in the absorption spectrum, between 550 and 750 nm, as 0.6, 1.2, 1.7, 2.3, 2.8, and 3.8 equiv of CuCl was added to Co(II)-TTP-2D. (b) Plot of the change in the absorption spectrum, between 550 and 750 nm, as 0.6, 1.2, 1.7, 2.3, 2.8, and 3.8 equiv of ZnCl2 was added to Co(II)-TTP-2D. (c) Plot of the absorption spectrum at 650 nm as a function of either added Cu(I) or Zn(II). Titrations were performed with 16.5 μM Apo-TTP-2D in 200 mM HEPES, 100 mM NaCl, at pH 7.5.
