A novel covalently linked binuclear phthalocyanine 1 was synthesized by the "double-click" reaction. The UV-vis and fluorescence spectra and electrochemistry revealed that the geometry of 1 is a closed clamshell conformation in which a strong electronic interaction is observed between the two Pc moieties.

A robust molecule that resists degradation via nucleophilic, electrophilic and radical attacks is described. Coordinated O(2) is reduced catalytically, producing efficiently thyil radicals in spite of the extreme electronic deficiency of the catalyst.

2(3),9(10),16(17),23(24)-tetrakis-2,6-dimethoxyphenoxy substituted magnesium (II) phthalocyanine, which has very good solubility in polar and non-polar solvents does not aggregate, was synthesized. Its structure characterized by spectroscopic methods such as elemental analysis, UV-vis, FT-IR, MALDI-TOF mass 1H NMR. It aprotic dimethyl sulfoxide, N, N- Dimethylformamide, tetrahydrofuran, dichlor...

In this study, we systematically investigated the adsorption of chloroaluminum phthalocyanine (ClAlPc) on SiO2 (100) surface using molecular dynamics (MD) combined density functional theory including a semiempirical dispersion correction (DFT-D). Chloroaluminum phthalocyanine (ClAlPc) molecule can adsorb on surfaces in two distinct adsorption configurations, depending on if the central Cl atom ...

Raman spectra of zinc phthalocyanine monolayers, adsorbed on gold and on glassy carbon surfaces (electrodes), are presented. These spectra have been recorded with the electrodes inside and outside an electrochemical cell filled with an aqueous electrolyte. A confocal Raman microspectrometer was used. It was demonstrated that, because this spectrometer uses low laser intensities, no damage of th...

Synthetic methods to obtain selectively sulfonated metallo phthalocyanines are compared. Both condensation and direct sulfonation procedures lead to mixtures of monoto tetrasulfonated products which are resolved by reverse phase liquid chromatography in buffered aqueous-methanol. The proportion of sulfonated derivatives is examined as a function of the starting reagents in the case of the conde...

This review covers the synthesis of coumarin-porphyrin, coumarin-phthalocyanine and coumarin-corrole conjugates and their potential applications. While coumarin-phthalocyanine conjugates were obtained almost exclusively by tetramerization of coumarin-functionalized phthalonitriles, coumarin-porphyrin and coumarin-corrole conjugates were prepared by complementary approaches: (a) direct synthesis...

We succeeded to fabricate p-n heterojunction and bulkheterojunction small-molecular-weight organic thin-film solar cells by combination of dry (p-type = zinc phthalocyanine, n-type = fullerene) and wet (p-type = tetra-tert-butyl zinc phthalocyanine, n-type = [6,6]-phenylC61-buteric acid methyl ester) processes. Relationship between morphologies of semiconducting layers and photovoltaic properti...

This review presents studies devoted to the description and comprehension of phenomena connected with the sensing behaviour towards NO(2) of films of two phthalocyanines, titanium bis-phthalocyanine and ruthenium phthalocyanine. Spectroscopic, conductometric, and morphological features recorded during exposure to the gas are explained and the mechanisms of gas-molecule interaction are also eluc...
