摘　　要：Photochromic polymer is defined as a series of materials based on photochromic units in polymer chains,which produces reversible color changes under irradiation with a particular wavelength.Currently,as the research progresses,it shows increasing potential applications in various fields,such as anti-counterfeiting,information storage,super-resolution imaging,and logic gates.However,there is a paucity of published reviews on the topic of photochromic polymers.Herein,this review discusses and summarizes the research progress and prospects of such materials,mainly summarizing the basic mechanisms,classification,and applications of azobenzene,spiropyran,and diarylethene photochromic polymers.Moreover,3-dimensional(3D)printable photochromic polymers are worthy to be summarized specifically because of its innovative approach for practical application;meanwhile,the developing 3D printing technology has shown increasing potential opportunities for better applications.Finally,the current challenges and future directions of photochromic polymer materials are summarized.
