摘要:
                                The complex formation of zinc 2,8,12,18-tetramethyl-3,7,13,17-tetraethylporphyrinate, 5,17-bis(zinc 2,8,12,18-tetramethyl-3,7,13,17-tetraethyl-10-phenylporphyrinate)-25,27-dimethoxy-26,28-dihydroxycalic-[4]-arene, and 5,17-bis(zinc 2,8,12,18-tetramethyl-3,7,13,17-tetraethyl-10-phenylporphyrinate)-25,27-dimethoxy-26,28-crwon-[6]-calix-[4]-arene with 1,2-diaminoethane, 1,3-diaminopropane, and 1,2-di-(dimethylamino)ethane in toluene was studied by spectrophotometric molar ratio method and H-1 NMR. The effect of the diamine structure on the formation of "internal" and "external" porphyrinate-ligand complexes of the composition 1 :1 and 1 :2 was established. The stability constants of the complexes obtained were calculated and the concentration intervals of their formation were determined.
