Summary The metal complexes ofmeso-tetrakis (p-tolyl) porphine (TTP) are chromatographed on octadecyl-bonded silica gel thin-layer with various organic solvents of relatively high polarity used as the eluent. The mobility of the metal-TTP complex depends on its centralmetal, increasing in the order of Cu(II)〈Pd(II)≈NI(II)〈TTP free acid〈V(IV) as vanadyl〈Zn(II)〈Mg(II), although some irregularities are found with the different developing solvents used. The concept of Hildebrand's solubility parameter is applied to the discussion of the mobility of each compound, on the solvents used as the developer. Successful separation of the TTP compounds is performed by using a mixture of acetone and acetonitrile as the developer, although the Ni- and Pd-complexes are not completely resolved.
