“…All the measurements were not performed on the complex CoBPc due to the paramagnetic nature of the cobalt metal cation. As shown Scheme 1, compounds 3-7 were synthesised as follows: 3,4-bis(3,4-dicyanophenoxy)benzoic acid (3) was synthesized by the known method [18]. Compound 2 (1.78 g, 11.55 mmol) was dissolved in dry DMSO (15 mL), and compound 1 (4.00 g, 23.11 mmol) was added under argon atmosphere.…”

“…Ceyhan et al showed that the BPc derivative had higher oxygen reduction performance than that of its own monomeric species [43]. Recently, few studies have reported the non-linear optic properties with Z-Scan techniques [18,22,23,29,30]. Generally, in UV-vis spectra of all the reported studies, the interaction between Pc rings or two metal centres and substituents is noteworthy.…”

The synthesis of ball-type binuclear metal-free (H 2 BPc) and metallic (magnesium (MgBPc), cobalt (CoBPc), and zinc (ZnBPc)) phthalocyanine derivatives containing four benzoic acid substituents at the peripheral positions is described. The new compounds were fully characterized using elemental analysis, mass spectrometry, fourier-transform infrared, 1 H nuclear magnetic resonance and electronic spectroscopies. The Q band absorptions in DMSO were observed at 675/702 for H 2 BPc, at 668/698 for MgBPc, 672 nm for CoBPc and 681 nm for ZnBPc. Considering their potential application as photosensitisers in photodynamic therapy, the fluorescence quantum yield, triplet quantum yield, and singlet oxygen quantum yield of the diamagnetic derivatives was determined, and photodegredation quantum yields and magnetic circular dicroism measurements were performed for all complexes. The triplet lifetime value of the MgBPc was found to be larger than that of the metal-free and zinc counterparts, which were 60 μs, 130 μs and 60 μs, respectively. H 2 BPc, MgBPc and ZnBPc were obtained singlet oxygen quantum yield of 0.03, 0.06 and 0.40 while the tiplet quantum yield were 0.84, 0.91 and 0.93 in DMSO, respectively.

“…Prolifically, Nyokong’s group reported the NLO properties of several phthalocyanine-based hybrid materials, of which we highlight compound 35 – 38 ( Figure 15 ) [ 146 , 147 , 148 ]. For instance, double- and triple-decker phthalocyanines 35-QD and 36-QD were linked to mercaptosuccinic acid-capped ternary CdSeTe/CdTeS/ZnSeS quantum dots (QD), and their optical power limiting (OPL) properties were evaluated by the open-aperture Z-scan technique (532 nm laser and pulse rate of 10 ns) [ 146 ].…”

“…A comparison with similar hybrid materials continuing other central moieties demonstrated that the In(III) containing complexes showed the best OPL performance, limiting thresholds of 0.14 and 0.12 for 36a and 36b , respectively. In sequence, the same group covalently attached a ball-type indium phthalocyanine to glutathione capped (Ag, Au, CdTeSe, CdTeSe/ZnO) nanoparticles [ 148 ]. The optical limiting threshold ranged from 0.40 to 0.78 J/cm 2 , with the complex 37a accounting for the most improved triplet state parameters and nonlinear optical behavior (0.40 J/cm 2 ).…”

Phthalocyanines have enjoyed throughout the years the benefits of being exquisite compounds with many favorable properties arising from the straightforward and diverse possibilities of their structural modulation. Last decades appreciated a steady growth in applications for phthalocyanines, particularly those dependent on their great photophysical properties, now used in several cutting-edge technologies, particularly in photonic applications. Judging by the vivid reports currently provided by many researchers around the world, the spotlight remains assured. This review deals with the use of phthalocyanine molecules in innovative materials in photo-applications. Beyond a comprehensive view on the recent discoveries, a critical review of the most acclaimed/considered reports is the driving force, providing a brief and direct insight on the latest milestones in phthalocyanine photonic-based science.

“…Phthalocyanine complexes can get a sulfur-containing substituent due to the formation of conjugates with nanoparticles. N. Nwaji et al [97] described a series of conjugates of nanoparticles (Au, Ag) and quantum dots (CdTeSe, CdTeSe/ZnO) with ball-type indium phthalocyaninate (Scheme 28).…”

Synthetic approaches to the phthalocyanines and their polynuclear and sandwich-type derivatives, bearing sulfurcontaining functional groups, are classified. Additionally complexes, possessing an extended π-conjugation system (planar and sandwich-type 2,3-naphthalocyanines) are reviewed. Principal application areas are covered. Special attention is paid to the formation of conjugates with gold nanoparticles -prospective materials for organic electronics.
