| چکیده مقاله |
| A mesoporous imine-linked triazine-based covalent organic polymer (Triazine-COP) was synthesized via an ultrasonication-assisted Schiff-base condensation between 2,4,6-tris(4-formylphenoxy)-1,3,5-triazine and 4,4′-oxydianiline.[1] The resulting material features a high surface area, good structural stability, and a nitrogen-rich framework suitable for binding Au(III) ions. Reduction with NaBH₄ generated uniformly dispersed gold nanoclusters within the polymer matrix, forming the hybrid catalyst Au-NCs@Triazine-COP. This nanostructured catalyst exhibited excellent activity in the A³ coupling of alkynes, aldehydes, and amines, affording propargylamines in high yields across substrates with diverse electronic properties. Its strong performance is attributed to the accessible porous channels that enhance dispersion and reactivity of the metal nanoclusters.[2] The catalyst remained effective for at least seven consecutive cycles with minimal loss of activity. The overall synthetic pathway of the Triazine-COP framework is shown in Scheme 1. |
