Porous Organic Frameworks for Catalysis
Abstract
POFs possess high stability, high surface area, tuned pore size, adjustable
skeletons, and etc. POFs provide the versatile platforms for catalytic applications.
Through the pre-synthetic and post-synthetic strategies, POFs with catalytic perfor-
mance could be achieved. In this chapter, we introduce two types of catalysts. One is
POFs with metal-containing site as catalysts and the other is special organic groups
as heterogeneous catalyst. Furthermore, POFs could be served as catalyst support
owing to their high surface area and various coordinating sites. The typical strategies
for the synthesis of catalytic POFs are also presented.

5.1 Introduction
It has been documented that POFs possess various porous structures, high stability,
and adjustable skeletons. Thus a multipurpose platform has been established of
which POFs have been employed for catalytic applications [

]. Commonly,
there are two promising strategies to achieve this requirement (Fig.
5.1
). One is
directly synthesis of catalytic POFs by introducing building blocks contain-
ing active catalytic groups; the other is via post-synthetic method, of which the
active catalyst is combined with the original POF materials by post-synthetic treat-
ment. Based on the types of active catalyst, two major classes will be introduced:
(1) POFs t with metal-containing site as catalysts; (2) POFs with incorporate rigid
organic building blocks as heterogeneous catalysts. In this chapter, we will present
the strategy for constructing catalytic POFs and their applications.
