The invention belongs to the technical field of force stimulus response photoluminescence materials, and particularly relates to a diphenylamine molecule and polyurethane composite material with a force stimulus response phosphorescence function and a preparation method and application of the diphenylamine molecule and polyurethane composite material. The preparation method comprises the following steps: designing and synthesizing a series of diphenylamine type derivatives with hydrogen-donating groups, and physically blending the diphenylamine type derivatives with a certain content into polyurethane with power-donating groups to obtain the force stimulation response material. The material is a composite material capable of enhancing light-excited phosphorescence and prolonging the luminescence service life along with the increase of elongation, shows force stimulation response based on phosphorescence change, has the advantages of large luminescence signal-to-noise ratio and high sensitivity, has high mecha
