Embodiment 1
[0081] When fullerene is C 70 , M is zinc (Zn), n=15, the fullerene phthalocyanine derivatives are as shown in formula 1-1, and the preparation method includes:
[0082] (1) Add 0.12 millimoles of C 70 , 1.4 millimoles of N-ethylglycine (purchased from Alfa; as a reaction material), 1.4 millimoles of p-carboxybenzaldehyde (purchased from Alfa; as a reaction material) were dissolved in 150 ml of toluene solution (purchased from Bailingwei; As the solvent), under the protection of argon atmosphere, the reaction was stirred at 110°C for 6 hours, and most of the solvent was removed by rotary evaporation. The compound was separated by silica gel column to obtain the compound represented by formula 4-1. The compound and 10 microliters of N,N-dimethylformamide (purchased from Bailingwei; as a catalyst) were added to 20 ml of anhydrous dichloromethane (purchased from Bailingwei; as a solvent), and at 0°C, 2.3 millimoles of grass were added Acyl chloride (purchased from Inokia; used as an...
Embodiment 2
[0097] The photodegradation stability test of the fullerene phthalocyanine derivatives represented by formula 1-1 obtained in Example 1 is as follows:
[0098] (1) Prepare a DMSO solution of the fullerene phthalocyanine derivative represented by formula 1-1 obtained at 10 micromol / liter in Example 1 (a) and 10 micromol / liter tetracarboxylic acid phthalein represented by formula 2-1 The DMSO solution of cyanine (b) was exposed to 650 nm red light for different times (0, 10, 20, 30, 40, 50, 60, 90 minutes), and then measured its UV-Vis absorption spectrum and UV-Vis The characteristic absorption intensity at 685nm in the absorption spectrum changes with the illumination time, and the results are shown in Figure 5(a), Figure 5(b) and Figure 5(c) respectively.
[0099] As the illumination time increases, if the change in UV-Vis absorption intensity is smaller, the sample is more stable and the ability to resist photobleaching is stronger. It can be seen from Figure 5(b) and Figure 5(c...
Embodiment 3
[0101] The dark toxicity test was performed on the fullerene phthalocyanine derivatives represented by formula 1-1 obtained in Example 1. The steps and results are as follows:
[0102] (1) Resuscitate Hela cells (Cell Resource Center, Shanghai Institutes for Biological Sciences, Chinese Academy of Sciences), and adjust the cell density to 5×10 when the cells enter the log phase and the growth is stable. 4 / Ml, planted in 96-well plate, 37℃, 5% CO 2 , Incubate for 24 hours;
[0103] (2) After the cells adhere to the wall, replace the DMEM solution (Corning R10-013-CV, purchase company: Baierdi) with 200 microliters of 0 (as a control), 4.5, 9, 13.5, 18, 22.5 , 27 micromol / L of the DMEM solution of the fullerene phthalocyanine derivatives obtained in Example 1, 37 ℃, 5% CO 2 , Incubate for 24 hours in the dark;
[0104] (3) Discard the DMEM solution containing the fullerene phthalocyanine derivatives obtained in Example 1, add 10% CCK-8 (Dojindo Molecular Technologies, Inc) colorless D...
