AbstractCovalent organic frameworks (COFs) are a class of porous organic polymers with designable and predictable platform that may provide new opportunities to develop a metal-free in-situ prepared photocatalyst by condensation method. Currently, we have designed a new class of two dimensional covalent organic frameworks (2DCOFs), which is important for further growth in this promising field for boosting selective solar chemical productions under solar light. For this scientific research work, perylene-3, 4, 9, 10-tetracarboxylic dianhydried (PDAH) and tetraaniline-4, 4′, 4″, 4‴-(ethene-1, 1, 2, 2-tetrayl) (TAET) have been attached by a condensation method first time to the fabrication of in-situ 2DCOFs photocatalyst. The photocatalyst-biocatalyst attached system urbanized using 2DCOFs as photocatalyst functions in a highly selective manner, leading to high NADH regeneration (83.68%), followed by its consumption in L-glutamate production (89.95%) from α-ketoglutarate. In this article, in-situ prepared photocatalyst has an excellent solar light-harvesting ability, band gap suitability, and highly organized π-electron channels are very applicable for highly selective solar chemical (L-glutamate) production and expected to trigger further interest in developing flexible films for solar energy transformation applications.
