The Synthesis of Symmetrical Phthalocyanines

Unsymmetrically Substituted Phthalocyanine Carboxylic Acids

“…All compounds were characterized by 1 H NMR, IR and ESI-MS spectra. It is necessary to point out that the compounds 6 and 7 are not single compounds but mixtures of positional isomers; the structural formula show only one of four possible isomers for each compound (same as in the case of symmetrically tetrasubstituted phthalocyanines [18] ).…”

Photophysical, Photochemical, and BQ Quenching Properties of Zinc Phthalocyanines with Fused or Interrupted Extended Conjugation

“…where 0 and are the fluorescence intensities of fluorophore in the absence and presence of quencher, respectively. The ratios of 0 / were calculated and plotted against [BQ] according to (2), and SV is determined from the slope.…”

“…Phthalocyanines (Pcs) are remarkable macrocyclic compounds having magnificent physical and chemical properties [1]. Metallophthalocyanines (MPc) have been investigated in detail for many years due to their high chemical and thermal stability, high degree of aromaticity, and synthetic flexibility [2,3]. They have also found different applications in many fields ranging from industrial [4], technological [5,6] to medical [7,8].…”

“…We have recently reported on the synthesis, characterization, and photophysical and photochemical properties of [2,9,16,23-tetra-(salicylaldimino)phthtalocyaninatozinc(II)] and [2,9,16,23-Tetra-{8-hydroxyquinolinato-salicydenaminatozinc(II)}phthtalocyaninato-zinc(II)] [21]. In this work the photophysical and photochemical properties of tetrasubstituted zinc-phthalocyanines with unsaturated cinnamaldimine moieties attached to the inner core through phenoxy-bridges [22] and a new water-soluble tetracationic zinc phthalocyanine [23] which contains four conjugated Schiff 's base groups at the peripheral positions are reported.…”

Synthesis, spectroscopic, and cellular properties of α-pegylated cis-A2B2- and A3B-types ZnPcs

“…Phthalocyanines (Pcs) are a class of tetrapyrrolic macrocycles related to the naturally occurring porphyrins; compared with the porphyrin ring, Pcs exhibit an extended 18 π-electron system with four benzene units fused onto the β-pyrrolic positions and nitrogen atoms at the meso -positions instead of the methine bridges in porphyrins [1, 2]. These structural features confer to Pcs a number of properties that make them highly desirable for a variety of applications in biology, medicine and materials science, including strong absorptions and emissions in the near-IR, high stability and easy macrocycle derivatization.…”
