Abstract: Metal nanoparticles in porous supports are of great importance for catalysis, separation and sensing, but their controllable preparation is still largely unmet. Herein, we describe a simple laser-induced synthesis of ultrafine gold nanoparticles in the covalent organic framework. Gold nanoparticles are well embedded, and they are about (1±0.1) nm in size. This work is universal for the preparation of well-dispersed and ultrafine metal nanoparticles in porous supports.
