Chlorophyll is the most abundant photocatalytic pigment that enables plants to absorb solar energy and convert it to energy storage molecules. Herein, we report a tandem photocatalytic approach utilizing the natural pigment chlorophyll in crude form to achieve photoinduced electron transfer (PET) and energy transfer (EnT) towards the oxidative functionalization of indoles.

叶绿素是最丰富的光催化颜料,使植物能够吸收太阳能并将其转化为能量存储分子。在本文中,我们报告了一种串联光催化方法,该方法利用天然形式的天然色素叶绿素实现了对吲哚的氧化功能化的光致电子转移(PET)和能量转移(EnT)。氧化还原电势,ESR,荧光猝灭和紫外线实验已经证明了叶绿素的双重催化活性。该研究的重点是叶绿素的自动串联光催化作用,以分子氧作为氧化剂,水作为反应介质,并利用光谱可见区的光化学能,使吲哚绿色氧化。
