Interaction between nickel hydroxy phthalocyanine derivatives with p-chlorophenol: Linking electrochemistry experiments with theory
Khene, Samson,Lobb, Kevin,Nyokong, Tebello
, p. 706 - 716 (2010)
In this work the interaction between peripherally (β) substituted nickel tetrahydroxyphthalocyanines (β-NiPc(OH)4 and β-Ni(O)Pc(OH)4) with p-chlorophenol is theoretically rationalised by performing calculations at B3LYP/6-31G(d) level. Density functional theory (DFT) and molecular orbital theory are used to calculate the condensed Fukui function for phthalocyanine derivatives and p-chlorophenol, in order to determine the reactive sites involved when p-chlorophenol is oxidized, and to compare theoretically predicted reactivity to experimentally determined electrocatalytic activity. Electrocatalytic activities of adsorbed NiPc derivatives: ads-α-NiPc(OH)8-OPGE (OPGE = ordinary poly graphite electrode), ads-α-NiPc(OH)4-OPGE and ads-β-NiPc(OH)4-OPGE are compared with those of the polymerized counterparts: poly-α-Ni(O)Pc(OH)8-OPGE, poly-α-NiPc(OH) 4-OPGE and poly-β-NiPc(OH)4-OPGE, respectively.

The present invention provides methods for increasing stability and efficiency of organic perovskite materials for use in various electronic devices. In particular, methods of the invention use a non-peripheral substituted phthalocyanine for passivating d
Breaching the wall: morphological control of efficacy of phthalocyanine-based photoantimicrobials

An efficient treatment of infections using antimicrobial photodynamic therapy (aPDT) anticipates that uptake of photosensitizer (PS) by bacterial cells is very fast and effective. In this work, the design, synthesis, characterization, and photodynamic activity of amphiphilic, water-soluble zinc(ii)phthalocyanine (Zn(ii)Pc) molecules bearing none, three or six thiophenyl moieties are described. We show that PSs that contain no or flexible substituents on non-peripheral positions can photoinactivate microbes at very low loading concentrations and low light doses. In contrast, a PS derivative that contains non-flexible substituents is rendered less effective, despite an increased generation of cytotoxic singlet oxygen, higher lipophilicity and a lower tendency to aggregate. Our unexpected finding emphasizes the role of the morphology of PSs in bacterial cell-molecule interactions and suggests another relevant and hitherto disregarded characteristic to improve PS design.
