The invention relates to the technical field of material chemistry, and provides an aperture regulation and control method and application of a naphthalimide hydrogen bond organic framework. By changing the ratio of N, N-dimethylformamide to water, the hydrogen bond interaction between water and 2, 7-bis (4H-1, 2, 4-triazole-4-yl) benzo [lmn] [3, 8] phenanthroline-1, 3, 6, 8 (2H, 7H)-tetraone is changed, so that the pore size of the naphthalimido hydrogen bond organic framework is regulated and controlled.
