Synthesis, electrochemical, in-situ spectroelectrochemical and in-situ electrocolorimetric characterization of new phthalocyanines containing macrocyclic moieties
synthesized newphthalocyanine compounds containing optically active 1,1′-binaphthyl crown ethers units. The metal-free phthalocyanine (3) was synthesized by the cyclotetramerization of dinitrile derivative (2) in dry n-pentanol by a classical method. However, metalphthalocyaninescomplexes (4, 5, 6), were synthesized by the reaction of dinitrile derivative (2) in DMAE. The structure of the new compounds
