The invention discloses a Fe(III) ion fluorescent probe and a preparation method thereof. The preparation method of the Fe(III) ionic fluorescent probe comprises the following steps: first, carrying out an amidation on 3,3',4,4'-diphenyltetracarboxylic dianhydride and 4-pyridinylmethanamine to obtain N,N'-bis(4-pyridyl methyl) biphthalimide; and then self-assembling AgClO4 and N,N'-bis(4-pyridyl methyl) biphthalimide to obtain the Fe(III) ionic fluorescent probe. The fluorescent probe is an Ag(I) coordinate polymer which has the characteristics of being high in porosity, large in specific surface area, regular in duct dimension, adjustable in size of framework and the like, can be used as the fluorescent probe to monitor and recognize Fe(III) ions without being processed, and is simple toprepare and operate, excellent thermal stability, good in selectivity and quick to monitor. 本发明公开了种Fe(III)离子荧光探针及其制备方法，该Fe(III)离子荧光探针的制备方法如下：先将3,3',4,4'-联苯四甲酸二酐和4-吡啶甲胺进行酰胺化反应，得到N,N'-双(4-吡啶基甲基)二邻苯二甲酰亚胺，再将AgClO和N,N'-双(4-吡啶基甲基)二
