To improve the solubility and recyclability of the NIR photocatalyst, two synthetic strategies, namely “living” polymers with permanent NIR photocatalyst by reversible addition-fragmentation chain transfer (RAFT) polymerization and “non-living” polymers with recyclable NIR macro-photocatalyst (macro-PC) by conventional radical polymerization, were developed by copolymerization of hydrophilic and polymerizable zinc phthalocyanine (ZnTAPc-MAm or ZnTAPc-Am) monomers. The resultant macro-PCs from RAFT polymerization were endowed with permanent NIR photocatalysis due to the attachment of zinc phthalocyanine moieties, and the features of both “living” and permanent NIR photocatalyst of the “living” macro-PCs were verified by much simple multiple chain extensions via RAFT polymerization in water (only involved in “living” polymers and fresh monomer) under irradiation with NIR LED light (λ_max = 730 nm) at room temperature. In addition, the resultant water-soluble “non-living” macro-PCs from conventional radical polymerization were endowed with only NIR photocatalysis property but they could be easily recycled just by centrifugation, which facilitates to synthesize tailored polymers by recyclable PCs under NIR irradiation.

为了提高近红外光催化剂的溶解度和可回收性，有两种合成策略，即通过可逆加成-断裂链转移（RAFT）聚合具有永久近红外光催化剂的“活性”聚合物和具有可回收近红外宏观光催化剂（宏观）的“非活性”聚合物。 -PC）通过传统的自由基聚合，通过亲水性和可聚合的锌酞菁（ZnTAPc-MAm或ZnTAPc-Am）单体的共聚而开发。由于连接了锌酞菁部分，RAFT 聚合所得的大 PC 具有永久的近红外光催化作用， 室温下，λ _{max = 730 nm）。}此外，传统自由基聚合所得的水溶性“非活性”大PC仅具有近红外光催化性能，但只需离心即可轻松回收，这有助于在近红外照射下通过可回收PC合成定制聚合物。
