Special Issue Information

Dear Colleagues,

Porphyrins, corroles, phthalocyanines, and other tetrapyrrolic macrocycles are versatile molecular platforms with wide-ranging applications in fields such as environmental remediation, energy conversion, and biomedicine. Their strong absorption in the visible region, photochemical robustness, and adaptable coordination chemistry make them excellent candidates for incorporation into functional materials, including metal–organic frameworks (MOFs), covalent organic frameworks (COFs), carbon-based nanomaterials (graphene, carbon dots, carbon nanotubes), and polymeric systems.

Structural modifications—whether through peripheral substitution or axial metal coordination—allow for fine-tuning of redox, photophysical, and catalytic properties. These features are critical to improving performance in reactive oxygen species generation, photocatalytic degradation of pollutants, solar energy harvesting, and photodynamic therapy, among other applications.

This Special Issue aims to gather original research and review articles focused on porphyrins and related macrocycles. Topics may include their synthesis, functionalization, photochemical behavior, and diverse applications in catalysis, energy, sensing, and medicine. Contributions addressing hybrid materials and sustainable technologies are welcome, but the scope is not limited to these areas. We invite authors to share both fundamental and applied studies that reflect the continued relevance and innovation of porphyrinoid-based systems in contemporary science.

The oxidation of chlorophenolic compounds is essential for converting these persistent and toxic pollutants into less harmful products, thereby reducing their environmental and health impacts. In this study, a p-coumaric acid ester derivative was employed as the starting material to synthesize the corresponding phthalonitrile precursor (EnCA-CN), followed by the preparation of non-peripherally substituted Co(II) and Cu(II) phthalocyanine complexes (EnCA-Copc and EnCA-CuPc). These complexes were subsequently characterized using a range of spectroscopic techniques and designed to engage in π–π interactions with graphitic carbon nitride to form efficient photocatalytic materials. The structures of the two effective catalysts were characterized by FT-IR, SEM, and XRD analyses, after which their photocatalytic performance and recyclability in the degradation of 2-chlorophenol, 2,3-dichlorophenol, and 2,3,6-trimethylphenol were evaluated. The optimum catalyst loading for the MPc/g-C3N4 composites was determined to be 0.5 g/L, yielding the highest photocatalytic efficiency. The EnCA-CoPc/g-C3N4 catalyst achieved 90.8% product selectivity and 82.6% conversion in the oxidation of 2-chlorophenol, whereas the EnCA-CuPc/g-C3N4 catalyst exhibited approximately 80.0% pollutant removal. The degradation efficiencies followed the order 2-CP > 2,3-DCP > 2,3,6-TCP, with benzoquinone derivatives identified as the major oxidation products. In recyclability tests, both catalysts retained more than 50% of their activity after five cycles; EnCA-CoPc/g-C3N4 maintained 68% conversion in the 5th cycle, while EnCA-CuPc/g-C3N4 retained 60% conversion in the 4th cycle.
