Water soluble novel phthalocyanines containing dodeca-amino groups

Characterization of Metal Phthalocyanine Catalysts Using Field Desorption Mass Spectrometry

“…The electronic properties of monomeric and polymeric complexes are generally characterized by cyclic voltammetry and spectroelectrochemistry. UV-Vis, infrared (IR) and Raman spectroscopy have also been widely used to characterize different metal phthalocyanines used as catalyst (Sesalan et al, 2008). From the IR characteristics of alkyl groups, some characteristic vibrational fundamentals due to the phthalocyanine rings and the substituents, the structures of phthalocyanine complex could be assigned (Orti and Bredas, 1990;Fanli et al, 2003).…”

“…Tyapochkin and Kozliak (2005) reported binding and kinetic studies of complexation of thiolates salts with tetrasulfato cobalt (II) phthalocyanine using ultraviolet-visible (UV-Vis) spectrophotometry under anaerobic conditions. A number of analytical techniques have been used to determine the structure and molecular weight of phthalocyanines (Orti and Bredas, 1990;Fanli et al, 2003;Sesalan et al, 2008). The electronic properties of monomeric and polymeric complexes are generally characterized by cyclic voltammetry and spectroelectrochemistry.…”

Phthalocyanines prepared from 4-chloro-/4-hexylthio-5-(4-phenyloxyacetic acid)phthalonitriles and functionalization of the related phthalocyanines with hydroxymethylferrocene

“…For aqueous solutions it is necessary to introduce hydrophilic chemical functional groups into benzene rings of the basic pc skeleton [9]. The hydrophilic moieties which have been incorporated on the peripheral positions of pc ring include sulfonates [9][10][11], carboxylates [2,5,10,12], phosphonates [13], and quaternarized amino groups [14][15][16].…”

Highly positive-charged zinc(II) phthalocyanine as non-aggregated and efficient antifungal photosensitizer

“…These kinds of substituents with big steric effect were generally introduced into the β-positions of phthalocyanine ring due to easier preparation. 20,21,32 Considering that substitution at α-position of phthalocyanine skeleton can more efficiently prevent phthalocyanine from aggregation and provide more high singlet oxygen quantum yield than that at β-position, 33 in this work, we synthesize the tetra-α-substituted ZnPcs and examine their photochemical properties, cellular uptakes, and in vitro…”

“…17,18 Although lots of efforts have been devoted to overcome aggregation of phthalocyanines, only a few ZnPcs have been reported so far which exist in a monomeric form in aqueous media in the absence of disaggregation agents. [19][20][21][22][23][24] On the other hand, ZnPcs-based photosensitizer have not been reported to present specific affinity to fungal cells over human cells. Even for the other kinds of photosensitizer, only a few examples, which generally need to be conjugated with cost and complex macromolecules, were reported with high PDI potency toward fungi cells.…”
