Phtalocyanine in wässeriger Lösung I

Abstract: Makrocyclische Systeme mit vier Pyrrolringen sind in der Natur sehr weit verbreitet und haben infolge ihrer biologisch wichtigen Funktionen immer wieder das Interesse der Forschung auf sich gezogen. Solche Verbindungen konnen in Form ihrer Metallchelate Wirkungsgruppen von Fermenten darstellenl). Am haufigsten wird die Funktion des zentralen Metallions in diesen Komplexen von Magnesium oder Eisen ubernommen, doch konnten auch Kupfer 2), Mangan 3 ) , Vanadium4) und Kobalt nachgewiesen werden.In Anbetracht der b… Show more

“…This is consistent with the 3-4 order of magnitude difference between K D of CuPcX4 in benzene (13,14) and CuTsPc in water (3,4,6). In contrast, the KD values of Zn and VO phthalocyanines are approximately of the same order for MPcX4 in benzene (13,14) and MTsPc in water (3)(4)(5).…”

“…The values of K D measured for these cobalt neopentoxy complexes in DCB are 2-3 orders of magnitude smaller than for CoTsPc in aqueous solution (1)(2)(3)(4)7). This is consistent with the 3-4 order of magnitude difference between K D of CuPcX4 in benzene (13,14) and CuTsPc in water (3,4,6).…”

“…Unfortunately, working with sulfonated PCs (SPCs) poses some problems since most of them are present in aqueous media as dimers and possibly as higher aggregates, even at very low concentrations. Their dimerization constants are in the range 105-10s M-' (Bernauer and Fallab, 1961;Sigeletal., 1971;Darwentetal., 1982~). One notable exception is aluminum (111) sulfonated PC, which is largely monomeric in water solution (Danvent et al, 1982a).…”

“…Metal free sulfonated PC also'has a double peak when monomeric. In contrast, metallo PCs and sulfonated PCs have only one major peak in the red whether they are in the form of dimers or monomers (Bernauer and Fallab, 1961;Harriman and Richoux, 1980). As an example, in aqueous buffer at pH 7.4, zinc TSPC (largely dimeric) has a relatively broad, low absorption peak at 634 nm.…”
