Conjugated porous polymers (CPPs) have recently emerged as a new class of visible light-active, organic and heterogeneous photocatalysts for visible light-mediated photoredox reactions. The CPPs have been established as a potential alternative to resolve critical drawbacks of traditional molecular and homogeneous photocatalysts due to their structural durability, non-toxicity, low cost due to the absence of noble metals, and high designability. Tremendous attempts have been made toward the design and synthesis of CPPs for a variety of visible light-promoted photocatalytic chemical transformations. Nevertheless, the concomitant design protocols of CPPs have not been well structured so far. Herein, in this review, we aim to summarize the recent developments in controlling the structural, photophysical and electronic properties of CPPs, and thereby extract the underlying design principles. According to the principle of the photocatalytic process, key parameters for the molecular design of CPPs were described in three sections: (1) light absorbance by energy band gap, (2) charge separation and transport, and (3) electron transfer to the target substrate. The macroscopic features, i.e. morphology, porosity and chemical functionality, and processibility of CPPs were also presented for the enhancement of their photocatalytic activity.

设计用于可见光驱动的光催化化学转化的共轭多孔聚合物

共轭多孔聚合物（CPPs）作为一种新型的可见光活性，有机和非均相光催化剂，最近已经出现，用于可见光介导的光氧化还原反应。由于CPP的结构耐用性，无毒，由于没有贵金属而导致的低成本以及高设计性，因此已被确定为解决传统分子和均相光催化剂关键缺点的潜在替代品。已经针对各种可见光促进的光催化化学转化的CPP的设计和合成进行了巨大的尝试。然而，到目前为止，CPP的伴随设计协议还没有很好地构建。本文中，我们旨在总结控制CPP的结构，光物理和电子特性的最新进展，从而提取基本的设计原则。根据光催化过程的原理，CPP分子设计的关键参数分为以下三个部分：（1）能带隙的吸光度；（2）电荷的分离和传输；（3）电子转移到目标基质。宏观特征即形态，孔隙度和化学官能团，和每次通话费用的可加工性也提出了他们的光催化活性的提高。
