In this study, (ethylsulfanyl) porphyrazines have been modified with one peripheral ruthenium bipyridine groups. These compounds possess (bpy)2RuII moieties directly attached to the β position in the (ethylsulfanyl) porphyrazines through thioether chelation. The new compounds have been characterized by elemental analysis, FT-IR, ¹H-NMR spectroscopy and mass spectra. The spectral properties such as electronic spectra, aggregation and fluorescence of compounds have been studied in THF. Insertion of (bpy)2RuII moiety on the porphyrazines structure have been investigated photophysical properties of the complexes. [ABSTRACT FROM AUTHOR]

A new phthalonitrile precursor with tyrosine substituent and the zinc phthalocyanine derived from it were synthesized and their interaction with diphenylborinic acid was studied. The new compounds were characterized by using elemental analysis, IR, 1 H and 11 B-NMR and UV-VIS spectral data. 11 B-NMR data demonstrated that boron atom attached to the phthalonitrile precursor is in a bulky tetra-coordinated state with the formation of a coordinative N-B bond while completely planar phthalocyanine moieties with high aggregation tendencies at the concentrations used in NMR measurements lead the borinic ester side of the molecule into a planar tri-coordinated form. Moreover, the consequences of the presence of diphenylborinic ester groups on the spectral, photophysical and photochemical properties of the new zinc phthalocyanine are investigated in detail.

Abstract: The synthesis of novel, hexadeca-substituted metal-free and zinc(II)phthalocyanines bearing naphthoxy groups and chloro groups in peripheral positions and hexyloxy groups in non-peripheral positions is described. These phthalocyanines were characterized with elemental analyses, mass, proton nuclear magnetic resonance (1H NMR), fourier transform infrared spectroscopy (FT-IR) and ultraviolet–visible spectroscopy (UV–vis) techniques. Aggregation properties of these compounds were investigated in the different concentration range. The influences of the substituent on the hexadeca-substituted phthalocyanine framework and metal ion on the spectroscopic and photophysical properties have been investigated. The energy transfer to phthalocyanine core and radiative decays of the naphthol emission and phthalocyanine core were examined. [Copyright &y& Elsevier]

A novel zinc(II) phthalocyanine substituted with four diphenylborinic ester units was synthesized by the reaction of 2,9,16,23-tetra (salicylaldimino)-phthtalocyaninatozinc(II) and triphenylborane in THF at reflux condition. The novel zinc phthalocyanine was characterized by using elemental analysis, IR, 1 H and 11 B-NMR and UV–Vis spectral data. 11 B-NMR data demonstrated that the boron atom is in tetracoordinated state and diphenylborinate substituents have a cyclic structure with a coordinative N–B bond enhancing the stability of this borinated phthalocyanine derivative. Moreover, the consequences of the presence of diphenylborinic ester groups on the spectral, photophysical and photochemical properties of the new zinc phthalocyanine are investigated in detail.
