17. a) The mica flakes were prepared by grinding a mica sheet in a small blade mill for 10 min with water or water/ethanol mixture, followed by complete drying under vacuum. The size of the flakes ranged from about 1 to 10 μm.
18. b) The adsorption isotherm may be influenced by the edge/step sites on small mica flakes, yielding an overestimation for the adsorption capacity. However, the measurements would give us semi-quantitative considerations on the adsorption behavior of TMPyP on a flat mica surface.

22. At [TMPyP] = 10 μM, the AFM image (Figure 1b) exhibited a featureless flat surface, so that definitive geometry identification of the adsorbed species was not, unfortunately, possible.
23. At [TMPyP] = 1.0 μM, aggregation (or π-π stacking) of TMPyP did not occur at the mica/solution interface as judged from the mean height of the adsorbed molecules obtained by AFM.
