“…The typical shielding of inner core protons belonging to the metal-free Pc (8), which are generally located in the negative ppm region, 33 were not observed because of strong aggregation. 34 In the 1 H NMR spectra of lead(II) (9) and zinc(II) (10) Pcs, the resonances belonging to the methyl groups were observed at δ : 2.46 and 1.58 ppm for compound 9 and at δ : 2.45 and 1.69 ppm for compound 10. The aromatic protons were observed in the range of δ : 7.89-7.18 ppm for compound 9 and δ : 8.00-7.16 ppm for compound 10.…”

The complexes of peripherally tetra-substituted metal-free (8), lead(II) (9), and zinc(II) (10) phthalocyanine derivatives were synthesized for the first time in this work. The structures of these new complex compounds have been elucidated using many spectral methods such as electronic absorption, FT-IR, 1 H NMR, 13 C NMR, elemental analysis, and mass spectra. The thermogravimetric behavior of compounds 8-10 was determined by thermogravimetric analysis method in addition to these spectral methods.

“…For this reason, the yield of metal-free phthalocyanines (H 2 Pc) is low compared to MPcs. The central atoms of phthalocyanines and the substituent groups found in the structure significantly affect their chemical properties [1][2][3].…”

The primary goal of this work is to explore how the introduction of the Nickel (II) phthalocyanine tetrasulfonic acid tetrasodium salt (NiTsPc) organic interlayer influences the performance of conventional metal/semiconductor diodes. Firstly, the optical features of the NiTsPc organic film formed onto glass substrate were investigated. For this, the UV-Vis spectroscopic data were used to determine various optical parameters like absorption coefficient (), extinction coefficient (k), and refractive index (n). Then, Al/NiTsPc/p-Si diode was produced by forming ohmic and rectifier contact. The current-voltage (I-V) measurements were analyzed taking into account thermionic emission (TE) approach at room temperature. Device parameters such as ideality factor (η), barrier height (Φb), and resistance were investigated with the help of I-V technique. The Al/p-Si structure containing NiTsPc film showed good rectifying properties. In this analysis, Φb and η values were determined as 0.83 eV and 1.41, respectively, at room temperature. The device represents photovoltaic features with open-circuit voltage (Voc) of 0.37 V and a short-circuit current (Isc) of 8.17 µA under illumination of 100 mWcm-2. The results represent that the produced junction can be utilized in different photoelectric applications.

“…To explore the structure–activity relationship of this group further, it is important to investigate the anti-cancer efficacy and specificity of new phthalocyanine complexes, which may shed light on the cytotoxicity of these compounds during clinical therapy of different types of cancer. To this end, new synthetic procedures involving template processes have emerged as a possibility to overcome the low yield and purity of metal–phthalocyanine species (Kantekin et al, 2006 ; Alzeer et al, 2009 ; Bartlett et al, 2018 ) that are usually obtained in reported synthetic procedures. Metal–phthalocyanine complexes (MPcs) have had their photochemical and photophysical extensively explored, but photobiological assays involving these complexes have been described less frequently (Nyokong, 2007 ; Lourenço et al, 2014 ; Ahmetali et al, 2019 ; Uslan et al, 2019 ).…”

This work presents a new procedure to synthesize ruthenium–phthalocyanine complexes and uses diverse spectroscopic techniques to characterize trans-[RuCl(Pc)DMSO] (I) (Pc = phthalocyanine) and trans-[Ru(Pc)(4-ampy)2] (II) (4-ampy = 4-aminopyridine). The triplet excited-state lifetimes of (I) measured by nanosecond transient absorption showed that two processes occurred, one around 15 ns and the other around 3.8 μs. Axial ligands seemed to affect the singlet oxygen quantum yield. Yields of 0.62 and 0.14 were achieved for (I) and (II), respectively. The lower value obtained for (II) probably resulted from secondary reactions of singlet oxygen in the presence of the ruthenium complex. We also investigate how axial ligands in the ruthenium–phthalocyanine complexes affect their photo-bioactivity in B16F10 murine melanoma cells. In the case of (I) at 1 μmol/L, photosensitization with 5.95 J/cm2 provided B16F10 cell viability of 6%, showing that (I) was more active than (II) at the same concentration. Furthermore, (II) was detected intracellularly in B16F10 cell extracts. The behavior of the evaluated ruthenium–phthalocyanine complexes point to the potential use of (I) as a metal-based drug in clinical therapy. Changes in axial ligands can modulate the photosensitizer activity of the ruthenium phthalocyanine complexes.
