5. 2 (0.1 mmol) were dissolved in 2 mL of anhydrous THF and 5-(p-bromomethylphenyl)-10,15,10-tri-p-tolylporphyrin (0.1 mmol) in 1 mL of THF was added at room temperature. After stirring at room temperature for 24 h, the solvent was evaporated. Purification on Sephadex LH-20 (THF) followed by Sephadex G-10 (water) afforded the product in 40 % yield.
6. In water, the UV-vis spectrum of 1 shows peaks at 422 nm (log ε = 5.4) and at 648 nm (log ε = 3.8).
