Design, syntheses, spectroscopic, aggregation properties of novel peripheral octa-substituted zinc(II), magnesium(II) and lead(II) phthalocyanines and investigation of their photocatalytic properties on the photooxidation of 4-nitrophenol

Investigation of photocatalytic properties of cobalt phthalocyanines on benzyl alcohol photoxidation

“…Due to Co +2 is paramagnetic metals, 1 H‐NMR spectra of P‐CoPc and Q‐CoPc cannot be taken. [ 57,58 ] When the UV‐Vis spectra, which is the most important indicator of the formation of phthalocyanines, are examined, Q bands of cobalt phthalocyanines were observed at 661 nm, and B bands of these compounds were observed at 329 nm for P‐CoPc and 322 nm for Q‐CoPc in the DMSO at a concentration of 1.0 × 10 −5 M. In the mass spectra, for P‐CoPc , molecular ion peak was observed at m/z : 1447.91 [M] + , and for Q‐CoPc , molecular ion peak was observed at m/z : 1200.11 [M + ] (Figures S3 and S4). The data obtained prove the formation of the pyridine/quinoline substituted cobalt phthalocyanines.…”

Peripherally, non-peripherally and axially pyrazoline-fused phthalocyanines: synthesis, aggregation behaviour, fluorescence, singlet oxygen generation, and photodegradation studies

“…In this regard, phthalocyanines containing dimethoxy groups increase solubility and can be used for various applications. 16,[26][27][28][29] Pyrazoline derivatives, which are members of heterocyclic compounds, are interesting compounds with a diverse biological profile spectrum, drug design, and synthetic versatility. The pyrazoline skeleton has been widely studied by many researchers in the field of medicinal chemistry for different diseases.…”

Quinoline‐fused both non‐peripheral and peripheral ZnIIand MgIIphthalocyanines: Anti‐cholinesterase, anti‐α‐glucosidase, DNA nuclease, antioxidant activities, and in silico studies

“…Phthalocyanines (Pcs) are aromatic macrocyclic compounds used in various applications due to their different binding positions, various coordination properties, and good spectroscopic characteristics. [17,18] Phthalocyanine compounds are used in many contemporary application areas such as photoluminescence, [19] photocatalytic, [20] photothermal activity, [21] non-linear optical (NLO), [22] and photodynamic therapy. [23] The aggregation and low solubility of these compounds in known organic solvents restrict their use in many modern biological applications.…”
