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 (crystal-
line 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.

2.1 Introduction
In this chapter, we discuss the principles for the synthesis of porous organic frame-
works (POFs). In POF material synthesis, there are two most vital factors that
attract our attention. One is the monomers, which are the fundamental constructing
units for the synthesis of POFs, and the other is the polymerization reactions.
The structures and properties of POFs are greatly affected by the utilization of
monomers and polymerization reactions. With regard to monomers, their corre-
sponding reactive groups and their spatial configurations play extremely impor-
tant roles, which determine the choice of polymerization reaction and the final
structure of POFs (Fig.

). In addition, based on the types of employed reac-
tions, monomers are reasonably designed and prepared to satisfy corresponding
demands. Therefore, in considering how to prepare POFs with permanent pores,
