Chemiluminescence (CL) of a metal–phthalocyanine complex was studied, and an analytical application of CL detection-flow injection analysis (FIA) of L-tyrosine was developed. The CL reaction of iron (III)–phthalocyanine tetrasulfonic acid (Fe–PTS) was examined using eight metals (Cu, Fe, Ni, Co, Mg, Pd, Pt and Zn)–phthalocyanine complexes. The CL signal immediately appeared, when the Fe-PTS aqu...

Highly ordered discrete assemblies of chlorophylls that are found in natural light-harvesting antennae are key to photosynthesis, which converts light energy to chemical energy and is the principal producer of organic matter on Earth. Porphyrins and phthalocyanines, which are analogues of chlorophylls, exhibit a strong absorbance of visible and near-infrared light, respectively. A highly ordere...

Two novel homologous series of phthalocyanines were prepared from 2,2-dialkylindane and 2,2-dialkyl-1,3-benzodioxole precursors. It was anticipated that attaching alkyl chains to five-membered rings, fused to the peripheral sites of the phthalocyanine ring, would result in the adoption of an out-of-plane configuration and thereby discourage cofacial aggregation, to provide an analogy with picke...

The present study reports on the preparation and the cell viability assay of two nanoemulsions loaded with magnetic nanoparticle and chloroaluminum phthalocyanine. The preparations contain equal amount of chloroaluminum phthalocyanine (0.05 mg/mL) but different contents of magnetic nanoparticle (0.15 10 or 1.50 10 particle/mL). The human bone marrow mesenchymal stem cell line was used as the mo...

Hydrogen sulfide (H2S) is an important signaling molecule that exerts action on various bioinorganic targets. Despite this importance, few studies have investigated the differential reactivity of the physiologically relevant H2S and HS(-) protonation states with metal complexes. Here we report the distinct reactivity of H2S and HS(-) with zinc(II) and cobalt(II) phthalocyanine (Pc) complexes an...

We here report our experimental study of the quantum size effect modulated metalation reaction of phthalocyanine (H(2)Pc) by low temperature scanning tunneling microscopy. When iron atoms were deposited onto Pb(111) thin films (2-5 nm thick) precovered by a self-assembled H(2)Pc monolayer, a surface metalation reaction to iron phthalocyanine (FePc) was observed. The amount of the FePc products ...

Phthalocyanines, a class of macrocyclic, square planar molecules, are extensively studied as semiconductor materials for chemical sensors, dye-sensitized solar cells, and other applications. In this study, we use angular dependent near-edge x-ray absorption fine structure (NEXAFS) spectroscopy as a quantitative probe of the orientation and electronic structure of H2-, Fe-, Co-, and Cu-phthalocy...

SWNT-porphyrin/phthalocyanine conjugates are described and fully characterised; their optical and electrochemical properties are investigated.

We disclose here the synthesis of a novel trifluoroethoxy-coated binuclear Pc which is the first example of a never-closing clamshell Pc.
