Накратко на български

Художествените пигменти в старите картини могат да създават синглетен кислород под влияние на светлината, който разгражда боите. Разбирането на този процес помага за по-доброто опазване на културното наследство и предлага приложения в медицината и пречистването на води.

The photo-reactivity of artistic pigments: from the preservation of historical paintings to new opportunities as singlet oxygen generators

Singlet oxygen is a highly reactive oxygen species known for its strong oxidative properties. Certain materials, known as singlet oxygen generators, produce this compound when exposed to light and in the presence of oxygen. These generators are sometimes found in the pigments used in historical paintings. The singlet oxygen they produce can significantly impact the preservation of these artworks, as it reacts with binding media and other pigments, leading to degradation processes that threaten their integrity. The primary objective of the PHOTOELECTROART project is to investigate the photo-reactivity of artistic pigments that generate singlet oxygen and to explore how this understanding can enhance the preservation of historical paintings containing these pigments. PHOTOELECTROART will employ an interdisciplinary approach, integrating photochemistry and infrared spectroscopy, including IR nanospectroscopy. The outcomes of this research will profoundly enhance our understanding of the role of singlet oxygen in the deterioration of historical paintings. By providing detailed insights into the degradation reactions that have occurred over time, the project will help identify effective preservation strategies for cultural heritage. Additionally, the findings will offer new information on the conditions that promote singlet oxygen generation from these pigments, contributing to innovative applications in fields such as wastewater treatment and medical therapies, where high singlet oxygen production is beneficial.

Цел на проекта

Singlet oxygen (SO) is one of the reactive oxygen species known for being a strong oxidant. There are materials, called SO generators, that produce SO under light exposure and in presence of oxygen. SO generators can be found even among the pigments used in historical paintings. SO has a huge impact in the preservation of these historical paintings since it reacts with the binding media and other artistic pigments causing degradation processes that compromises their integrity.The main goal of the PHOTOELECTROART project is to understand I) the photo-reactivity of artistic pigments that generate SO, II) the impact of the environment and microenvironment in the amount of SO emitted by these substances and III) how this can be applied to improve the preservation of historical paintings containing SO generator pigments. To achieve this, PHOTOELECTROART will exploit a highly interdisciplinary methodological process based on photo-electrochemistry and infrared spectroscopy, including IR nanospectroscopy.Results will have a major impact in the understanding of the role of the SO emitted by the pigments in the alterations of the historical paintings where these are found, providing a detailed knowledge of the degradation reactions throughout the painting’s history and helping to find suitable mitigation actions to preserve the cultural heritage. Additionally, the results will provide new information on the conditions that boost the generation of SO from those pigments: this new knowledge will contribute to the development of innovative applications in fields where a high production of SO is needed, such as treatment of wastewaters and medical therapies.
