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 novel Zn phthalocyanine bearing 4 salicylideniminophenyloxy substituents on peripheral positions was synthesized from the reaction of 4-aminophenoxy substituted phthalocyanine and salicylaldehyde. The condensation reaction of salicylidene Schiff base groups and benzeneboronic acid produced a new phthalocyanine carrying benzeneboronic acid ester derivatives as substituents. Ethoxy groups were bound to boronic acid as a second ligand. The presence of B-N bond interactions enhanced the stability of this boronated phthalocyanine derivative, which exhibited sufficient air stability during the purification and characterization processes. The novel compounds were characterized by using elemental analysis, IR, ¹H-NMR, 11 B-NMR, 13C-NMR, UV-Vis and MALDI-TOF MS spectral data. [ABSTRACT FROM AUTHOR]

Abstract: 4-(4-Formyl-3-hydroxyphenoxy)phthalonitrile (3) and its condensation product with 2-aminophenol have been synthesized to reach 4-(3-hydroxy-4-(((2-hydroxyphenyl)imino)-methyl)phenoxy)phthalonitrile (5), a tridentate ligand possessing ONO binding sites. Subsequent condensation of phenylboronic acid with 5 afforded a novel boronic ester of a Schiff base with a phthalonitrile group (7). Boronate 7 displays high stability and can be handled in air due to the presence of coordinative B–N and covalent B–O bonds in its structure. The novel compounds were characterized by elemental analyses, IR, UV–vis, mass, 1H-, 13C- and 11B NMR spectra. [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.
