Principles for the Synthesis of Porous Organic Frameworks

Abstract

To date, hundreds of porous organic frameworks (POFs) have been successfully designed and synthesized. With regard to POFs, the first important problem is the constructing strategies of POFs. In this chapter, we introduce some principles for the synthesis of POF materials. Based on the type of POFs (crystalline or amorphous), the discussion of POFs is classified into two parts. For the synthesis of POF materials, two most vital factors should be followed. One is the monomers that are the fundamental constructing units for the synthesis of POFs, and the other is the polymerization reactions. The structure and property of POFs are determined by the utilization of monomers and polymerization reactions. In other words, the synergistic effect of two factors could influence the chemical and physical characteristics of the resulting samples.

“…The present review does not address this issue. Unlike CPs, the classification of POPs is arguably easier, and main categories can be defined such as covalent organic frameworks (COFs), hyper-cross-linked polymers (HCPs), porous aromatic frameworks (PAFs), and various microporous polymers (PIMs, CMPs); see Figure . ,, Among this family of POP materials, the covalent organic frameworks (COFs) are in the majority under well-defined crystalline form. Finally, in the porous materials described above, while a large set is polymeric in nature, an array of organic porous materials are of oligomeric-type such as calixarenes, cryptophanes, and other cavitands …”
