International Journal of Photochemistry and Photochemical Research

International Journal of Photochemistry and Photochemical Research International Journal of Photochemistry and Photochemical Research is a peer-reviewed hybrid online journal launched in 2023 that is concerned with providing a platform to publish research in no time. All articles published here are peer-reviewed. Blue light systems, etiolated and de-etiolated growth patterns of plants, blue light photoreceptors, and phytochromobilin are a few topics that fall under this journal.

• Molecular photophysics: excited singlet and triplet state dynamics, radiative and nonradiative decay, fluorescence and phosphorescence, energy and electron transfer, quantum yield determination, time-resolved spectroscopy, and excited-state interactions in solution and solid phases.
• Photochemical reactions and mechanisms: photoisomerisation, photocycloaddition, photoinduced bond cleavage, photoalkylation, photosensitised transformations, photoredox synthetic methodology, and mechanistic and computational studies of photochemical pathways.
• Photocatalysis: semiconductor and molecular photocatalysts, photocatalytic pollutant degradation, photocatalytic hydrogen production, TiO₂, CdS, and composite catalyst systems, charge separation and recombination, and photocatalytic reactor design.
• Photoelectrochemistry and solar energy conversion: photoelectrochemical cells and water splitting, dye-sensitised solar cells, nanostructured photoelectrodes, semiconductor–electrolyte interface dynamics, photocurrent and impedance analysis, and electrochemical light-emitting cells.
• Photobiology of pigments and photoreceptor proteins: rhodopsin family proteins including bacteriorhodopsin, halorhodopsin, and proteorhodopsin, chromophore structure and photocycles, optogenetic tools, phototrophy, and light-driven ion transport.
• Plant photobiology: cryptochromes, phototropins, and LOV domains, phytochrome signalling, UVR8 and UV-B responses, phototropism and chloroplast movement, stomatal responses to blue light, photomorphogenesis, and light-regulated gene expression and growth.
• Photomedicine and photodynamic applications: photosensitiser design and photodynamic therapy, photothermal therapy, fluorescence imaging and diagnostic probes, antimicrobial photodynamic inactivation, and photobiological safety including blue-light hazard and optical radiation exposure.
• Luminescent and photoresponsive materials: carbon and graphene quantum dots, luminescent nanomaterials and nanocomposites, photodetectors and optoelectronic devices, photonic biosensors, flexible bioelectronics, and light-responsive polymers and coatings.
• Supramolecular and molecular photonic systems: photochemical logic gates and molecular switches, self-assembled light-responsive architectures, host–guest photochemistry, photoinduced charge transfer in supramolecular assemblies, and stimuli-responsive photofunctional systems.
• Environmental and atmospheric photochemistry: photolysis of pollutants in air and water, light-induced transformation of contaminants, photodegradation kinetics and transformation products, solar disinfection, and photochemical processes in natural waters.
