Beschreibungen/Notizen

• Metal Complexes of 5-[3′-(12-crown-4)methyloxy-carbonylphenyl]-15-phenylporphyrin (H 2 -MCEPP) are synthesized as the hosts which have two receptor sites, the crown ether moiety being for cations and the porphyrin-metal site for the counter anions. Cation or anion recognition is highly dependent on the porphyrin-metal; that is, the zinc complex (Zn-MCEPP) recognizes anions preferentially and, on the contrary, the magnesium complex (Mg-MCEPP) recognizes cations more effectively.
