摘要： 单线态氧（1O2）是一种高度反应活泼的物质，具有强氧化性，使其在光动力治疗、有机合成和材料科学等多个领域具有重要应用价值。然而，单线态氧的短寿命和高反应性为其实际应用带来了显著挑战。为克服这些挑战，开发高效的材料用于1O2的捕获与可控释放已引起了广泛关注。共价有机框架（COFs）因其独特的晶体结构、高孔隙度和优异的稳定性，成为理想的1O2存储和传输材料。在本研究中，我们设计并合成了以蒽为核心单元的二维COF（2D An COF），并进一步通过剥离得到纳米片（2D An COF-nanosheet），以提高其性能。荧光光谱分析表明，与块体COF相比，2D An COF纳米片表现出显著更高的1O2捕获速率，这归因于其更多暴露的活性位点。2D An COF及其剥离后的纳米片在外部热或光刺激下，1O?释放过程表现出优异的可逆性，且经过多次循环后性能无显著衰退。结果突显了二维COF材料，特别是纳米片形态，在1O?存储和释放中的高效和稳定潜力。本研究为设计1O2响应材料提供了新的理论见解，并为光动力治疗、光催化及其他需要精确控制反应性氧物种的领域开辟了新的应用前景。

Abstract: Singlet oxygen (1O2) is a highly reactive species with strong oxidizing properties, making it valuable in various applications, including photodynamic therapy, organic synthesis, and material science. However, its short lifetime and high reactivity present significant challenges in its practical use. To overcome these challenges, the development of efficient materials for 1O2 capture and controlled release has attracted considerable attention. Covalent organic frameworks (COFs), with their unique crystalline structure, high porosity, and exceptional stability, have emerged as ideal candidates for 1O? storage and transfer. In this study, we designed and synthesized a two-dimensional anthracene-based COF (2D An COF), which was further exfoliated into nanosheet (2D An COF-nanosheet) to enhance its performance. Fluorescence spectroscopy analysis demonstrated that the 2D An COF nanosheet exhibited a significantly higher 1O? capture rate compared to the bulk COF, which can be attributed to their more exposed active sites. Both the 2D An COF and its exfoliated nanosheet showed excellent reversibility in 1O2 release when exposed to external thermal or light stimuli, with no significant degradation in performance after multiple cycles. The results highlight the potential of 2D COF materials, particularly in nanosheet form, as efficient and stable platforms for 1O? storage and release. This work provides new theoretical insights into the design of 1O2-responsive materials and opens new avenues for applications in photodynamic therapy, photocatalysis, and other fields requiring precise control over reactive oxygen species.
