The selective production of fine chemicals using inexpensive solar light continues to be a challenge. As a means to achieve this we report herein the synthesis and development of a perylene-based solar-light-driven photocatalyst (PDA–DAA) obtained by the covalent bonding of perylene tetracarboxylic dianhydride (PDA) with a 2,6-diamino-anthraquinone (DAA) molecule. The photocatalyst/biocatalyst coupled system developed using PDA–DAA as a photocatalyst functions in a highly efficient manner, leading to high NADH regeneration (80.12%), followed by its consumption in exclusive production of l-glutamate (94.16%) from α-ketoglutarate. The present research highlights the development and application of the PDA–DAA photocatalyst for direct formation of l-glutamate under solar light.

高效的苝基聚合物光催化剂/生物催化剂系统,用于在太阳光下生产 l-谷氨酸

使用廉价的太阳光选择性生产精细化学品仍然是一个挑战。作为实现这一目标的一种手段,我们在此报告了通过苝四羧酸二酐 (PDA) 与 2,6-二氨基-蒽醌共价键合获得的苝基太阳光驱动光催化剂 (PDA-DAA) 的合成和开发。 (DAA) 分子。使用 PDA-DAA 作为光催化剂开发的光催化剂/生物催化剂耦合系统以高效的方式发挥作用,导致高 NADH 再生 (80.12%),然后消耗 α-酮戊二酸独家生产 l-谷氨酸 (94.16%) . 本研究重点介绍了 PDA-DAA 光催化剂在太阳光下直接形成 l-谷氨酸的开发和应用。
