[0064] Detection process of photoexcited electron transfer paramagnetic signal

[0065] (1) Metal fullerene Sc 3 N@C 80 The method for detecting electronic paramagnetic resonance spectroscopy properties of derivatives includes: dissolving about 0.5 mg of a sample in 1 mL of toluene solution, placing the solution in a quartz tube with a plug, and then testing the electronic paramagnetic signal (ESR) properties of the sample. First use ultraviolet light for a period of time, and detect metal fullerene Sc every four minutes 3 N@C 80 The ESR signal of the derivative is then used with visible light to detect the change of the ESR signal.

[0066] by figure 2 It can be seen that the metal fullerene Sc 3 N@C 80 There is no paramagnetic signal, and three characteristic lines appear after connecting small molecules of nitroxide radicals. Under the condition of ultraviolet light, the electron transfer in the molecule causes the decrease of the ESR signal (after 4 minutes of light, the ESR s...

Description

Technical field [0001] The invention relates to the technical field of molecular optical function switches, in particular to a metal fullerene derivative and a preparation method thereof, as well as a method for regulating the paramagnetic properties of the metal fullerene derivative and the use of the metal fullerene derivative as a molecular optical function Switch application. Background technique [0002] Metal fullerenes are mainly divided into two types: paramagnetism and diamagnetism, which are distinguished by whether they have spin single electrons. Metals or clusters are put into metal fullerenes to form embedded metal fullerenes, so that the internal groups are separated from the outside environment, and even highly reactive groups can exist stably inside. This allows the embedded metal fullerene to exist stably at room temperature, and has a long spin coherence time, and has a wide range of applications in the fields of quantum computing and communication. Because t...
