Synthesis and electrochemical and photoelectrochemical properties of polyphthalocyanine-coated electrodes

Dioxa-dithia Macrocycle-bridged Dimeric with Hexakis(alkylthio) Substituents and Network Polymer Phthalocyanines

“…A number of polymeric compounds based on repeating units containing phthalocyanine moieties have been synthesized in order to establish their photochemical and electrochemical properties [7][8][9]. Polymeric phthalocyanines are interesting compounds that exhibit qualities as catalysts and semiconductors [10].…”

Electroreduction of nitrate ions in concentrated sodium hydroxide solutions at lead, zinc, nickel, and phthalocyanine-modified electrodes

“…The z i n c and lead working e l e c t were obtained in accord with the literature [5]. Nickel sponge/ phthalocyanine electrodes were prepared in the same manner.…”

Synthesis of polymeric and low molecular weight phthalocyanines from nitriles and metal carbonyls on SiO2 and TiO2 and catalytic activities in the sulfide oxidation

“…Only in the case of Cu or CuCl 2 in the reaction with tetracarbonitriles structurally uniform 1, 2 with nitrile end groups and a molecular weight up to infinite were obtained. It was pointed out in the introduction that these experiences were extended to prepare thin films by the gas-phase reaction of tetracarbonitriles with a vapor-deposited Cu-film [4][5][6][7][8][9][10][11] or Co 2 -loaded inorganic carriers [12]. The process of chemical vapor deposition of thin reactive metal films by decomposition of metal carbonyls [26,27] was now used for the first time for the preparation of coatings of metals and also metal carbonyls on inorganic carriers followed by reactions with nitriles under conditions of phthalocyanine formation.…”

“…This method was also applied for coatings of low molecular weight phthalocyanines directly on the mentioned powdered inorganic carriers [12,13]. Compared to thin films of low molecular weight phthalocyanines (3), thin films of the analogous polymers (1, 2) can exhibit better electrical conductivities, and electrochemical and photoelectrochemical properties [4,[6][7][8][9][10][11].…”

“…One method uses in the first step the vapor deposition of copper on quartz, basal plane pyrolytic graphite, Ti plates or cleaved KCl crystals followed by reaction with tetracarbonitriles (1,2,4,5-tetracyanobenzene (4), diphthalonitriles such as 1,4-bis-(3,4-dicyanophenoxy)-benzene (5)) at $300 -400°C for $4-24 h in a closed bomb vessel [4][5][6][7][8][9][10][11]. Few reports describe the reaction of metal ion (Co 2 ) loaded powdered inorganic carriers (SiO 2 , g-Al 2 O 3 or active carbon) with tetracarbonitriles at higher temperatures in a closed bomb vessel under formation of coatings of 1 or 2 [12].…”
