Embodiment 1
[0027] In a 100 ml single-necked volumetric flask, add 0.0582 g of C 60 , 0.0110 grams of methyl / ethyl p-formylbenzoate, 0.0381 grams of sarcosine and 30 milliliters of toluene, refluxed at 115 ° C for 5 hours under nitrogen protection, separated and purified, and obtained methyl p-benzoate and ethyl p-benzoate substituted fullerene derivatives. Characterized by MALDI-TOF-MS, I, m / z calcd911.8; found911.1; II, m / z calcd925.9; found925.2.
Embodiment 2
[0029] Fullerene curds were prepared on wool fabric surface using fullerene derivative I.
[0030] Cut the wool fabric into square pieces of about 0.25 square centimeters in size with scissors, rinse the surface with acetone, and let it dry naturally; use a pipette gun to take out 20 μl of 1 mg / ml fullerene derivative I in chloroform-ethanol (volume ratio 10:1) solution, drop directly on the wool fabric substrate, and naturally volatilize until dry; spray gold on the substrate with fullerene self-assembly structure for 20 seconds, and observe with Hitachi TM-1000 scanning electron microscope, you can see the wool fabric The prepared fullerene curds on the surface of the fabric ( figure 1 ).
Embodiment 3
[0032] Preparation of fullerene curds on nylon plastic surface using fullerene derivative I.
[0033] Cut the nylon plastic into square pieces about 0.25 cm2 in size with scissors, rinse the surface with acetone, and let it dry naturally; use a pipette gun to take out 20 μl of 1 mg / ml fullerene derivative I in chloroform-ethanol (volume ratio 10:1) solution, drop directly on the nylon plastic substrate, and naturally volatilize to dryness; spray gold on the substrate with the fullerene self-assembly structure for 20 seconds, and observe with the Hitachi TM-1000 scanning electron microscope, you can see the nylon Fullerene curds prepared on plastic surfaces ( figure 2 ).
