Phthalocyanines metal complexes

Samsonova and Nikiforov, 1984), and porphyrin and phthalocyanine metal complexes (Becker et al., 1985a, 1986b Becker and Grossmann, 1990) were tested. That a series of relatively simple anions such as the oxalate monoanion, tetraphenyl bor-anate (Ph4B ), bromide, chloride, and even tetrafluoroborate can act as donors is, at least for the last mentioned anion, surprising, but Becker et al. (1985 b) were able to trap aryl radicals and in some cases also donor radicals (Cl, COO ) by spin trapping with nitrosodurene and phenyl-tert-butylnitrone. The photochemical effect is postulated to be due to ion pairs ArNJ X-.

In suptamolecular systems, in some cases (systems formed by addition of PVP, PEG, PDDA, SDS), partial or complete neutralization of the negative charge of the anionic form of the original bis-phthalocyanine is observed. In the case of micellar system CTABr lanthanide bis-phthalocyanines exist predominantly in the anionic form. The dependence of the optical density bis-phthalocyanine on their concentration in the composition of multicomponent systems revealed that in cases of different metal ions bis-phthalocyanine metal complex may be present in both molecular and associated forms. 

Phthalocyanine metal complexes in the multicomponent systems can be in three states [5] in the form of a monomer with narrow absorption band in the 665-675 nm [11-14], H-aggregates with their absorption band shifted relative to the monomer hypsochromically to -630 nm, and J-aggregates with an absorption band batho-chromically shifted relative to the monomer to wavelengths of 730-850 nm. H- and... 

Traditional template synthesis of metal phthalocyanines requires high temperatures to be used. In contrast, electrochemical template methods allow the highly efficient assembly of phthalocyanine-metal complexes in organic solvents under ambient conditions.
