    • The product is a mixture of several species (monomer, Zn(II)-coordinated dimer, trimer, etc.) in the 4/1 < 2.0 region, whereas the spectra are scarcely changed in the 4/1 ≥ 2.0 region. Under these conditions, one cannot observe tight isosbestic points but may consider that the stoichiometry is 2:1 in the high 4 concentration region. In Figure 1, although the isosbestic points are not tight, they do exist at 550, 575, and 600 nm. This lack of tight isobestic points is, as mentioned above, due to the mixture in the 4/1 < 2.0 region. The similar spectral situation is also adapted to the polymeric 4/2 system.

    • 4 M) in CH2C12 solvent was stirred at room temperature for 1 min. One drop of a 2 + 4 mixture in CH2C12 was placed on a carbon-coated grid on a filter paper. The drop immediately penetrated into the filter paper, and the grids were allowed to dry in air. This sample was coated with Pt under argon for 30 s.

    • The most stable conformations of 5 and 6 were estimated by computational methods (Discover 3/Insight II 98.0). As a result, we confirmed that the inclination angle of the meso-phenyl groups in 6 is larger than that in 5. Since the most stable conformation adopts 90°, one may consider that 5 is more stable than 6. The similar situation is also adapted to 7 and 8.
