Abstract

In this study molecular porphyrin chromophores have been successfully vitrified in AgPO₃ glass via a simple, low-temperature, post-melting encapsulation procedure. Their controlled incorporation within the phosphate glass network results to enhanced stability against visible light exposure while preserved their structural integrity. This simple method ensures the optical and electronic properties of porphyrins remain intact, rendering the developed composite porphyrin-glasses suitable for light-harvesting and photocatalytic applications. The AgPO₃ glass matrix acts as a protective barrier, shielding porphyrins from environmental factors. This scalable, cost-effective technique eliminates the need for chemical modifications or anchoring groups, offering a robust pathway for integrating molecular chromophores into transparent optical media for advanced functional applications.

期刊介绍： Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials. OPTICAL MATERIALS focuses on: • Optical Properties of Material Systems; • The Materials Aspects of Optical Phenomena; • The Materials Aspects of Devices and Applications. Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
