Covalent organic frameworks (COFs), a class of porous crystalline organic polymers, have emerged as promising materials for photocatalysis. Structural functionalization of COFs is an effective strategy to improve their photocatalytic performance. However, this approach is mainly limited within interior parts of COFs. Herein we report exterior functionalization of a one-dimensional (1D) COF by introducing terpyridine units on its edges to anchor Pt(II) cations. The as-obtained 1D COF (Pt-Tpy-COF) exhibits high photocatalytic activity for hydrogen evolution from water, with a hydrogen evolution rate up to 7.8 mmol g−1 h−1. Experimental studies and theoretical calculations reveal that the high performance of Pt-Tpy-COF benefits from its distinct 1D framework with readily accessible active sites. This study not only demonstrates the potential of 1D COFs as photocatalysts, but also provides valuable insights for the design and development of highly efficient catalysts for various catalytic applications based on the structural features of this new type of nanoporous crystalline framework materials.

一维共价有机框架的横向功能化，用于高效光催化从水中析氢
共价有机框架（COF）是一类多孔结晶有机聚合物，已成为有前景的光催化材料。 COF的结构功能化是提高其光催化性能的有效策略。然而，这种方法主要局限于 COF 的内部。在此，我们通过在其边缘引入三联吡啶单元来锚定 Pt(II) 阳离子来报道一维 (1D) COF 的外部功能化。所获得的一维COF（Pt-Tpy-COF）对从水中析氢表现出较高的光催化活性，析氢速率高达7.8 mmol g −1 h −1 。实验研究和理论计算表明，Pt-Tpy-COF 的高性能得益于其独特的一维框架和易于访问的活性位点。这项研究不仅展示了一维COF作为光催化剂的潜力，而且还为基于这种新型纳米多孔晶体框架材料的结构特征的各种催化应用的高效催化剂的设计和开发提供了宝贵的见解。
