The invention discloses a photochromic material as well as a preparation method and application thereof, and the photochromic material is a complex 1-[(1-(3-pyridyl)-2-(2-amino-3-pyridyl) ethylene)-(1, 3-phthalate) zinc] n or a complex 2-[(1, 3-bis (3-pyridyl)-2, 4-bis (2-amino-3-pyridyl)-cyclobutane) 0.5 (1, 3-phthalate) zinc] n. The complex 1 is a bright yellow crystal or powder. Under the catalysis of ultraviolet light, the complex 1 is converted into a complex 2, and the complex 2 is colorless crystal or white powder. The preparation method of the photochromic material is simple, the reaction condition is mild, and the light conversion rate is high. 本发明公开了一种光致变色材料及其制备方法和应用，其中光致变色材料为配合物1--[(1-(3-吡啶基)-2-(2-氨基-3-吡啶基)乙烯)-(1,3-苯二甲酸根)锌]n或配合物2--[(1,3-二(3-吡啶基)-2,4-二(2-氨基-3吡啶基)-环丁烷)0.5(1,3-苯二甲酸根)锌]n。配合物1为亮黄色的晶体或粉末。在紫外光的催化下，配合物1转化为配合物2，配合物2为无色的晶体或白色粉末。本发明光致变色材料的制备方法简单，反应条件温和，且光转化速率快。
