Synthesis of Porous Organic Polymers Via Catalytic Vapor-Assisted Solvent-Free Method

Solvent-free synthesis is one kind of important approach for the preparation of porous materials. However, the catalytic vapor generated during these processes is limitedly reported. Herein, a novel catalytic vapor-assisted solvent-free method was established for the preparation of porous organic polymers (POPs) by application of catalytic vapor derived from ferric chloride. After investigating the decisive factors of this approach, its versatility is examined by synthesizing POPs from multitudinous monomers. Most importantly, this study provides evidence that catalytic vapor is a simple and efficient catalyst to a general synthetic pathway for POPs. The catalytic vapor-assisted solvent-free method for the preparation of POPs proposed in this paper provides a feasible idea for the development of chemical vapor synthesis for porous materials.
