The adlayer structure of 5,10,15,20-tetrakis(N-methylpyridinium-4-yl)-21H,23H-porphyrin tetrakis(p-toluenesulfonate) (TMPyP) at an iodine-modified Pt(100)(I-Pt(100)) surface was investigated in HClO 4 solution by in situ scanning tunneling microscopy (STM). The structure of the iodine adlayer was (√2 x 5√2)R45°. TMPyP molecules were adsorbed with flat-lying orientation at the I-Pt(100)) surface and aligned along the (100) direction that was parallel to the row of iodine atoms.
