Reticular chemistry guided construction of Olympic rings-inspired two-dimensional covalent organic frameworks for photocatalysis.

ABSTRACT: Two-dimensional covalent organic frameworks (2D-COFs) have received extensive attention from structural design to application explorations. Top-down design and discovery of new structures of 2D-COFs still remains a great challenge. In this work, under the guidance of reticular chemistry, we rationally designed and synthesized four highly crystalline 2D-COFs (HIAM-0028 to HIAM-0031) inspired by the Olympic rings using hexatopic aldehydes and diamine-based building units through a C₆ + C₂ approach. Due to their capacity to generate reactive oxygen species and suitable electronic structures, these COFs can be used as heterogeneous photocatalysts for the cycloaddition reaction of tertiary anilines and maleimides. HIAM-0030 exhibits the best photocatalytic performance and
