Enhancing solar energy conversion efficiency is very important for developing renewable energy, protecting the environment, and producing agricultural products. Efficient enhancement of photophosphorylation is demonstrated by coupling artificial photoacid generators (PAGs) with chloroplasts. The encapsulation of small molecular long-lived PAGs in the thylakoid lumen is improved greatly by ultrasonication. Under visible-light irradiation, a fast intramolecular photoreaction of the PAG occurs and produces many protons, remarkably enhancing the proton gradient in situ. Consequently, compared to pure chloroplasts, the assembled natural-artificial hybrid demonstrates approximately 3.9 times greater adenosine triphosphate (ATP) production. This work will provide new opportunities for constructing enhanced solar energy conversion systems.
提高太阳能转换效率对于开发可再生能源、保护环境和生产农产品非常重要。通过将人工光合酸生成剂（PAG）与叶绿体结合，可有效地增强光磷酸化作用。通过超声处理，可大大提高 PAG 小分子长寿命物质在类囊体腔中的包封率。在可见光照射下，PAG 发生快速的分子内光反应，产生大量质子，显著增强了原位质子梯度。因此，与纯叶绿体相比，组装的天然-人工杂交体的三磷酸腺苷（ATP）产量增加了约 3.9 倍。这项工作将为构建增强型太阳能转换系统提供新的机会。
