We are pleased to launch this upcoming thematic issue, inviting cutting-edge original research, review articles and visionary perspectives focused on photochromic systems, molecular photoswitches, and light-responsive materials. Relevant advances spanning chemistry, materials science, physics, engineering, biomedicine and related interdisciplinary fields are highly encouraged.

Scope

Contributions covering (but not limited to) the following topics are welcome:

• Photochromic molecules and molecular photoswitches
• Light-responsive nanomaterials and hybrid systems
• Photopharmacology and light-activated therapeutics
• Smart biomaterials and adaptive molecular architectures
• Molecular machines and stimuli-responsive systems
• Advanced Raman, infrared, fluorescence, and ultrafast spectroscopies
• Time-resolved and operando spectroscopic investigations
• Computational photochemistry and excited-state dynamics
• Photocatalysis and solar-energy conversion processes
• Photoinduced charge-transfer and energy-transfer mechanisms
• Optical sensing and imaging technologies
• Spectroscopy-driven materials discovery and characterization

We especially encourage submissions bridging theory and experiment, featuring methodological innovation, or introducing emerging applications with prominent scientific and technological impact.
