Summary: An unsymmetrical zinc phthalocyanine dye containing six electron donating hexylsulfanyl groups and a pyrazole-3-carboxylic acid anchoring group was synthesized and evaluated for its photophysical, electrochemical, and theoretical characteristics as well as photovoltaic properties. The optimized dye-sensitized solar cell based on this dye exhibited an impressive power conversion efficiency of 2.52%, surpassing that of the reference dye under the same conditions. The improved performance is attributed to the conjugated anchoring group, leading to efficient electron injection.

Summary: Dye-sensitized solar cells (DSCs) are a promising alternative photovoltaic technology with low cost and high performance for indoor applications. Solid-state DSCs (ssDSCs) have been developed to address the problems of electrolyte leakage and electrode corrosion. However, the power conversion efficiency of ssDSCs is generally lower than traditional liquid DSCs. To overcome these limitations, the authors have developed an in situ photoelectrochemical polymerization (PEP) approach to synthesize polymer hole transport materials (HTMs) in the porous electrodes, enhancing pore infiltration fraction and conductivity. This review provides a comprehensive overview of material engineering and interfacial optimization for ssDSCs, as well as recent advances in PEP and its impact on device performance.

Summary: A simple and selective photoelectrochemical biosensor was developed for Hg2+ detection using zinc phthalocyanine dye-sensitized CdS and alginate as a carrier and binder. The biosensor exhibited a wide linear range and low detection limit, making it a promising platform for detecting other biomolecules. Detection of Hg2+ was achieved through specific binding with thymine-rich probe DNA, resulting in a decrease in photocurrent.

Summary: As cancer is a leading cause of death, exploring new sensitizers in photodynamic therapy (PDT) is highly desirable. In recent years, ultrasound-assisted PDT applications have gained attention. The importance of phthalocyanines as sensitizers in PDT and/or sonodynamic therapy (SDT) is increasing. This study focused on the synthesis of highly soluble non-peripherally substituted metal-free, gallium, and indium phthalocyanines to evaluate their potential in sonophotodynamic therapy (SPDT). The combination of ultrasound and light enhanced singlet oxygen production in all phthalocyanine derivatives, with indium phthalocyanine showing the highest applicability in PDT.

Summary: Recently, the combined application of synergistic therapies in photodynamic antimicrobial chemotherapy has become important for achieving more efficient results. In this study, the synergism between two sensitizers, rose bengal (RB) and chlorin e6 (Ce6), excited by different methods, was evaluated as a novel approach for both photodynamic and sonodynamic therapy against methicillin-resistant Staphylococcus aureus. Results showed that the dual synergism between RB and Ce6 achieved a >3 log reduction for certain molar ratios, while alone, the sensitizers excited by ultrasound and light only achieved approximately a 1 log reduction.

Summary: Cadmium zinc sulfoselenide (CdZnSSe) and reduced graphene oxide-cadmium zinc sulfoselenide (RGO)-CdZnSSe composite-based photoelectrodes were fabricated using a facile, simultaneous co-electrodeposition method for the first time. The rCV technique allowed for homogeneous decoration of CdZnSSe particles among RGO sheets, resulting in improved photoelectrochemical performance in hydrogen evolution. The Cd0.8Zn0.2S0.2Se0.8 photodecoration demonstrated the highest photocurrent density (4.08 mA cm-2), which was further increased to 5.00 mA cm-2 by decorating with RGO. The proposed rCV technique showed superiority in fabricating well-controlled RGO-CdZnSSe composite photoelectrodes.

Summary: In this study, the researchers aimed to improve the performance of zinc(ii) phthalocyanine (ZnPc) used as photosensitizers in dye-sensitized solar cells (DSSCs) by changing the number of anchoring groups and their spacers on ZnPc rings. Two new asymmetric ZnPcs were synthesized and their structures were characterized by various spectroscopic methods. The researchers found that the nature of the spacer groups and the number of anchoring groups played a significant role in enhancing the efficiency of DSSCs. ZnPc(6) with three benzoic acid and naphthoic acid anchoring groups, three benzene spacers, and one naphthalene spacer exhibited higher performance compared to ZnPc(7) with three benzoic acid anchoring groups and three benzene spacers.

Summary: Due to the high mortality rate of cancer worldwide, the development of new anticancer drugs has become a critical task. Phthalocyanines, specifically water-soluble sulfonated phthalocyanines, have gained attention as potential anticancer agents. In this study, we aimed to investigate the in vitro anticancer effectiveness of an alpha-substituted water-soluble cobalt phthalocyanine complex on prostate and breast cancer cells. The results showed that the complex exhibited cytotoxic and genotoxic effects, with a higher efficacy in prostate cancer cells. Further studies are required to fully explore the non-photoactivation anticancer potential of this complex.
