The invention discloses a chromogenic molecular probe, a test strip and a method for rapidly detecting uranyl ions, the probe is prepared from 4, 4-diphenyl ether dianhydride and 1, 2, 4-trihydroxybenzene as raw materials, and the reaction volume ratio of the probe to a uranyl nitrate aqueous solution is 1: 1. On the basis of the coordination chemistry principle, charge transfer can occur in a complex formed by the probe and uranyl ions, so that the absorption spectrum of the probe is changed, the color of a corresponding solution is changed from yellow to red, and sensitive visual detection of uranyl ions is achieved. Meanwhile, the uranyl ion detection test strip disclosed by the invention is rapid, efficient, portable, reliable and simple to operate, realizes on-site rapid detection of a surrounding water source environment under the conditions of nuclear emergency and the like, and provides a new thought for detection of other radionuclides. 本发明公开了一种快速检测铀酰离子的显色分子探针、试纸条及方法,该探针由4，4-联苯醚二酐和1，2，4-苯三酚为原料制备而成，探针
