The novel metal-free phthalocyanines 8 and 9 bearing four peripheral tetraaza-dithiahexaoxa cylindrical or spherical macrotricycles have been synthesized by tricyclo-tetramerization of isoindolinediimine derivatives of supercryptands 6 and 7 and were characterized by elemental analysis, 1 H and 13 C
The new metal-free phthalocyanines 9,10-fused symmetrically in the peripheral positions with four diazadithiatetraoxa and diazahexaoxamacrobicycles, respectively, have been synthesized by bicyclotetramerization of isoindolinediimine derivatives of cryptands 7 and 8 and characterized by elemental ana
