The aggregation and photochemistry of the copper (II) 3, 4 00, 4 00, 4 000-tetrasulfonated phthalocyanine, free base phthalocyanine and copper (II) phthalocyanine have been studied by UV–VIS absorption spectroscopy and resonance Raman spectroscopy (RRS). The vibrational mode n3 of (Cu(tsPc) 4K has been used as a probe in RRS measurements. The photochemistry of monomers and dimers of (Cu(tsPc) h...

The great potential of organic heterostructures for organic device applications is exemplified by the targeted engineering of the electronic properties of phthalocyanine-based systems. The transport properties of two different phthalocyanine systems, a pure copper phthalocyanine (CoPc) and a flourinated copper phthalocyanine-manganese phthalocyanine (F16CoPc/MnPc) heterostructure, are investiga...

A synthetic procedure has been developed for the preparation of a Zn-phthalocyanine peripherally substituted with a dodecaborane. The absorption spectrum of the derivative is typical of the phthalocyanine chromophore. Moreover, the boronated phthalocyanine exhibits a high photosensitizing efficiency against a model biological substrate, such as N-acetyl-L-tryptophanamide, and a singlet oxygen q...

Molecular hybrid catalysts, such as cobalt(II) phthalocyanine (CoPc) complexes anchored to multi-walled carbon nanotubes (MWCNTs), provide selective CO2 conversion toward CO with high current densities, exceeding 0.1 A cm?2 in microfluidic or zero-gap (membrane) electrolyzers. However, the practicality of electroreduction is essentially determined by catalyst stability against mechanical and (e...

Detection of volatile organic compound (VOC) vapors, which are known to have carcinogenic effects, is extremely important and necessary in many areas. In this work, the sensing properties a cobalt phthalocyanine (CoPc) thin film at six different VOC vapors (methanol, ethanol, butanol, isopropyl alcohol, acetone, ammonia) concentrations from 50 450 ppm investigated. sense, it observed that inter...

In the present work, resolution and quantification of mixtures different opiate compounds in presence common cutting agents using an electronic tongue (ET) is evaluated. More specifically, ternary heroin, morphine codeine were resolved caffeine paracetamol. To this aim, array three carbon screen-printed electrodes modified with ink-like solutions graphite, cobalt (II) phthalocyanine palladium, ...

The phthalocyanine dyes, Remazol Turquoise Blue G133, Everzol Turquoise Blue and Heligon Blue S4 are found to be biosorbed by Phanerochaete chrysosporium (white-rot fungi) and also metabolised by its ligninolytic extracellular enzymes resulting in dye decolourisation, formation of free copper ions and organic metabolites with ultimate extensive phthalocyanine ring breakdown. It is believed that...
