Summary The migration behavior of metal complexes ofmeso-tetrakis(p-tolyl)porphyrin (TTP) are studied in HPTLC systems with cellulose and silica gel thin-layers and various organic solvents of relatively low polarity. The mobility of the metal complex tends to increase in the following orders of its central-metal elements: on cellulose, Mg(II)〈Zn(II)〈V(IV)〈(H)〈Pd(II)〈 Ni(II)≈Cu(II); on silica gel, Mg(II)〈V(IV)〈Zn(II)= (H)〈Ni(II)≈Pd(II)⩽Cu(II). Recommendable phase system for the separation of metal-TTP complexes is a combination of silica gel thin-layer with a carbon disulfide-m-xylene mixture though the complexes of Ni, Cu and Pd are not completely resolved.
