“…To afford definite substitution products, the preferred routes start from the synthesis of properly substituted phthalonitriles. Once the derived Pcs are obtained, they could be further modified with the known organic synthesis tools [12]. However, unsymmetrically substituted phthalonitriles unavoidably afford isomeric mixtures of substituted Pcs.…”

Metallophthalocyanines as Catalysts in Aerobic Oxidation

The first remarkable property associated to metallophthalocyanines (MPcs) was their chemical “inertness”, which made and make them very attractive as stable and durable industrial dyes. Nevertheless, their rich redox chemistry was also explored in the last decades, making available a solid and detailed knowledge background for further studies on the suitability of MPcs as redox catalysts. An overlook of MPcs and their catalytic activity with dioxygen as oxidants will be discussed here with a special emphasis on the last decade. The mini-review begins with a short introduction to phthalocyanines, from their structure to their main features, going then through the redox chemistry of metallophthalocyanines and their catalytic activity in aerobic oxidation reactions. The most significant systems described in the literature comprise the oxidation of organosulfur compounds such as thiols and thiophenes, the functionalization of alkyl arenes, alcohols, olefins, among other substrates.

“…It was determined that its Q band in DMSO was shorter and less red shifted than ZnPcs containing different types of benzenesulfonamide-derived substituents in the literature [24,25]. This may be related to the binding of the novel benzenesulfonamide derivative, which contains strong electron acceptor groups that deactivate the ring, such as pyridine and bromine, at the peripheral positions of the phthalocyanine ring, resulting in less redshift of absorption in the NIR region [32] than its counterparts [24,25].…”

Novel (E)-4-((5-bromo-2-hydroxy-3-methoxybenzylidene)amino)-N-(pyridin-2-yl)benzenesulfonamide 1, (E)-4-((5-bromo-2-(3,4-dicyanophenoxy)-3-methoxybenzylidene)amino)-N-(pyridin-2-yl)benzene sulfonamide 2 and 2(3),9(10),16(17),23(24)-tetra-[(E)-4-((5-bromo-3-methoxy-2-(λ1-oxidanyl)benzyl idene)amino)-N-(pyridine-2-yl)benzenesulfonamide]phthalocyaninato zinc(II) phthalocyanine 3 were synthesized. Their (1-3) structures were illuminated with spectroscopic methods such as FT-IR, 1H NMR,13C NMR, UV–vis, MALDI-TOF mass spectra and also elemental analysis. The spectroscopic, photophysical and photochemical properties of the zinc(II) phthalocyanine 3 were investigated in dimethyl sulfoxide and its effects on the above mentioned properties were reported as a result of containing new type benzenesulfonamide derivatives as substituents. In addition, its above-mentioned properties were reported by comparing different species with those of their substituted and/or unsubstituted counterparts. The zinc(II) phthalocyanine 3 has photosensitizing abilities suitable and sufficient especially for photocatalytic applications.

“…Over the past 10 years, two reviews have been published devoted to the study of the role of substituents in the chemistry of phthalocyanines and their analogues. [29,30] However, they mention only a few examples of phthalocyanines substituted with sulfur-containing functional groups. Besides, these reviews do not provide data on the corresponding 2,3-naphthalocyanines, diphthalocyanines, and polynuclear complexes.…”

Synthetic approaches to the phthalocyanines and their polynuclear and sandwich-type derivatives, bearing sulfurcontaining functional groups, are classified. Additionally complexes, possessing an extended π-conjugation system (planar and sandwich-type 2,3-naphthalocyanines) are reviewed. Principal application areas are covered. Special attention is paid to the formation of conjugates with gold nanoparticles -prospective materials for organic electronics.
