The invention discloses a
triphenylamine polypyridine salt based
photosensitizer and a preparation method and an application of the
triphenylamine polypyridine salt based
photosensitizer, and belongsto the technical field of
biomedical engineering. The preparation method comprises enabling
triphenylamine monoaldehyde diiodine and 4-pyridineboronic acid to have a
coupling reaction, generating triphenylamine monoaldehyde
bipyridine, then enabling the triphenylamine monoaldehyde
bipyridine and an
electron withdrawing group to have a
condensation reaction, enabling an obtained product to have a salt forming reaction with iodomethane, and obtaining the
photosensitizer. The photosensitizer has the
electron withdrawing group, the
singlet oxygen is produced efficiently under the illumination condition, the purpose of rapidly efficiently killing a tumor
cell is fulfilled; the photosensitizer not only efficiently kills the tumor
cell and inhibits the growth of the tumor, but also monitors the death of the tumor
cell and a
tumor tissue in real time, and therefore, a photosensitizer
medicine can be used to judge the effect of the photosensitizer on the tumor cell. The preparation method of the photosensitizer is simple, and the cost is low.
