[0054] Metal Organic Framework Nanomaterial UiO-68-NH 2 Preparation of:

[0055] Weigh ZrCl 4 (19mg, 0.08mmol) was added to 3.2mL DMF, ultrasonically dispersed, then 240μL acetic acid was added for ultrasonically dispersed, and finally p-2,5-bis(4'-carboxyphenyl)aniline (H 2 -L) (28 mg, 0.08 mmol), sonicate to dissolve completely. Keep the temperature at 90°C for 48h, cool down to room temperature after 2h, and centrifuge at a high speed to obtain a solid, immerse the solid in DMF, stir and soak at 80°C for 6h, and centrifuge at a high speed. Then immerse the solid in absolute ethanol, stir and soak for 6 hours at 70° C., and centrifuge at a high speed to obtain solid powder. This operation was repeated 3 times. Finally, the solid was washed with ether and dried naturally to obtain a light yellow powder UiO-68-NH 2 .

Abstract

The invention provides a metal-organic framework nanomaterial loaded with ZnPc and having a novel structure as well as a preparation method of the metal-organic framework nanomaterial. The metal-organic framework nanomaterial loaded with ZnPc takes UiO-68-NH2 as a metal-organic framework nanomaterial and ZnPc as a photo-thermal conversion agent, the UiO-68-NH2 nanomaterial ZnPc@UiO-68-NH2 loaded with ZnPc is obtained by one-pot synthesis, and ZnPc in the ZnPc@UiO-68-NH2 compound is packaged in pores in the metal framework material UiO-68-NH2. The problems that pathalocyanine molecular aggregates in the prior art are prone to aggregation in an aqueous phase system as an anti-cancer photo-thermal conversion agent, poor in stability and the like are effectively solved, absorption peaks are subjected to red shift to a near infrared area to contribute to deep therapy, and the metal-organic framework nanomaterial has good actual application values.

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis of nanomaterials, in particular to a metal organic framework nanomaterial loaded with zinc phthalocyanine and its preparation method and application. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Phthalocyanine is a class of synthetic compounds with 18-electron conjugated large π system. Phthalocyanine has been used as a phototherapeutic material for tumors due to its strong absorption at 670-700 nm, high extinction coefficient, and tunable photophysical and photochemical properties through simple chemical modification. However, most phthalocyanines have poor biocompatibility in t...
