Non-covalent associates of metal phthalocyanines: the role of axial ligand and catalytic activity

Catalytically Active Systems of Cobalt Complexes with Wa-ter-Soluble Phthalocyanines

“…We previously found the macrocycle's structure and its coordination ability to play the key role for catalytic process. [56][57][58] DTC oxidation takes place in kinetic region upon constant oxygen and catalyst concentration as well as solution's pH. We approved earlier non-catalytic oxidation of DTC to be almost non-existent (k obs = 1.7•10 -5 s -1 ).…”

“…[60][61] Detailed analysis of coordination properties of studied phthalocyaninates is presented in. [58] It is worth mentioning only that there is dependence between stability of molecular complexes CoPc1-CoPc7 of 1:1 composition having various ligands and its catalytic properties upon RSH-substrates oxidation observed. Hence, one can conclude catalytic activity of metallophthalocyanines upon liquid-phase oxidation of DTC to be directly depended on both coordination center state, therefore type and stability of the associate in solution, and keeping coordination efficiency.…”

Synthesis, Spectroscopic Properties and Redox Behavior Kinetics of Rare-Earth Bistetrakis-4-[3-(3,4-dicyanophenoxy)phenoxy]phthalocyaninato Metal Complexes with Er, Lu and Yb

“…Phthalocyanines are widely used in many areas of activity, such as catalysis [ 1 , 2 ], light industry [ 3 , 4 ], medicine [ 5 , 6 ], linear and nonlinear optics and energy storage devices [ 7 , 8 , 9 ]. Such a widespread usage is associated with the high stability of these molecules, the presence of intense light absorption in the visible range, the flexibility of the design of structures [ 10 , 11 , 12 ], the possibility of introducing practically any metal atom into the central cavity [ 13 , 14 , 15 ] and the possession of significant coordination properties. The scope of usage directly depends on the structure of the molecule, namely on the nature of peripheral and non-peripheral substituents, the presence or absence of a central metal atom.…”

Investigation of Catalytic Processes of Thio-Compounds Conversion to Disulfides Using Novel Butyl/Butoxy-Phthalocyaninates of d-Metals

“…Substituted metal phthalocyanines have been used as materials [9] for many applications such as chemical sensors, [10][11][12] solar cells, [13][14][15][16] thin films, [17][18][19] liquid crystals, [20][21][22] optical data storage devices, electrochromic display devices, [23][24][25] photosensitizers for dye sensitized solar cells [13] and oxidation or reduction catalysts and photocatalysts, [26] photodynamic therapy. [27,28] In addition, varying the nature of the peripheral environment makes it possible to control the solubility of these compounds, [29,30] for example, the introduction of sulfonic, carboxylic or crown ether groups gives amphiphilicity to these compounds. Substitution by alkyl fragments makes it possible to obtain organosoluble metal phthalocyaninates with mesomorphic properties.…”
