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, 1H and 11B-NMR and UVVis spectral data. 11B-NMR data demonstrated that the boron atom is in tetracoordinated state and diphenylborinate substituents have a cyclic structure with a coordinative NB 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.
