The synthesis of a new macrobicyclic (cryptand) ligand 1,4,9,12,19,20,25,30-octaazabicyclo(10.10.10)dotriacontane, C4BISTREN and improved syntheses of the ligands 7,9,30-trioxa-1,4,10,13,16,22,-27,33-octaazabicyclo(11.11.11)pentatriacontane, OBISTREN and 1,13-dioxa-4,7,10,16,19,22-hexaazacyclotetracosane, OBISDIEN. The Co(II) complexes of these ligands are oxygen carriers. Among the six macrocyclic
新型大双环(穴状)配体1,4,9,12,19,20,25,30-八氮杂双环(10.10.10)dot康烷,C4BISTREN的合成以及配体7,9,30-trioxa-1的改进合成,4,10,13,16,22,-27,33-八氮杂双环(11.11.11)戊二烷,OBISTREN和1,13-dioxa-4,7,10,16,19,22-六氮杂环四氢烷,OBISDIEN。这些配体的Co(II)配合物是氧载体。在本文考虑的六个大环配体和六个大双环配体中,OBISTREN和OBISDIEN的双核钴(II)配合物形成最稳定的双氧配合物。
