Multicomponent reactions (MCRs) can be used to introduce different functionalities into highly stable covalent organic frameworks (COFs). In this work, the irreversible three-component Doebner reaction is utilized to synthesize four chemically stable quinoline-4-carboxylic acid DMCR-COFs (DMCR-1–3 and DMCR-1NH) equipped with an acid–base bifunctionality. These DMCR-COFs show superior photocatalytic H₂O₂ evolution (one of the most important industrial oxidants) compared to the imine COF analogue (Imine-1). This is achieved with sacrificial oxidants but also in pure water and under an oxygen or air atmosphere. Furthermore, the DMCR-COFs show high photostability, durability, and recyclability. MCR-COFs thus provide a viable materials’ platform for solar to chemical energy conversion.

通过太阳能驱动的 H2O2 生产的一锅多组分反应将双功能性和化学稳定性整合到共价有机框架中

多组分反应 (MCR) 可用于将不同的功能引入高度稳定的共价有机框架 (COF) 中。在这项工作中，利用不可逆的三组分 Doebner 反应合成了四种具有酸碱双功能的化学稳定的喹啉-4-羧酸 DMCR-COF（DMCR-1-3和DMCR-1NH）。与亚胺COF类似物₍ Imine - ₁). 这是通过牺牲氧化剂实现的，但也可以在纯水中和氧气或空气气氛下实现。此外，DMCR-COF 显示出高光稳定性、耐用性和可回收性。因此，MCR-COF 为太阳能到化学能的转换提供了一个可行的材料平台。
