One-Pot, One-Step Strategy for the Preparation of Clickable Melamine Based Microporous Organic Polymer Network

Abstract

Although, current preparation methods for microporous organic polymers (MOP) based on coupling or condensations reactions are simple and flexible, they suffer from the requirement of additional modification steps for introducing properties for specific purposes. In the present work, we have developed a simple and rapid synthetic strategy to prepare MOP possessing reactive sites to incorporate any molecules of interest by Click Chemistry. The clickable MOP with high surface area was readily synthesized through Schiff base chemistry using propargylated anthraquinone and melamine in the catalyst free, one-pot process. The versatility of the click coupling on the acetylene functional MOP was demonstrated on a model reaction using independently prepared fluorescent azido-pyrene.
