Embodiment 1
[0050] This embodiment provides a kind of synthetic method of carbon nanotube structure compound, and this method comprises the following steps:
[0051] Step 1, in the glove box, add Pd(OAc) sequentially into the sealed tube 2 (13.5mg, 0.06mmol), P(p-F-C 6 h 4 ) 3 (22.8mg, 0.072mmol), CsOPiv (42.1mg, 0.18mmol), Cs 2 CO 3 (560mg, 1.8mmol) and 60mL DMF were first stirred in the glove box for 5-10min, then compound 1 (273.6mg, 0.72mmol) and compound 2 (133.8mg, 0.6mmol) were added into a sealed tube. After the addition was complete, the sealed tube was taken out of the glove box and reacted at 130° C. for 20 h. After the reaction was completed, the reaction liquid was returned to room temperature, extracted with DCM and saturated ammonium chloride, and the extraction was repeated three times and the organic phase was collected. The organic phase was washed with anhydrous MgSO 4 Dry, filter with Celite, and spin dry. Separation by column chromatography (PE:EA=10:1, R f =...
Embodiment 2
[0065] This embodiment provides a kind of synthetic method of carbon nanotube structure compound, and this method comprises the following steps:
[0066] Step 1, in the glove box, add Pd(OAc) sequentially into the sealed tube 2 (135mg, 0.6mmol), P(p-F-C 6 h 4 ) 3 (228mg, 0.72mmol), CsOPiv (421mg, 1.8mmol), Cs 2 CO 3 (5.6g, 18mmol) and 60mL DMF were first stirred in the glove box for 5-10min, then compound 1 (2.7g, 7.2mmol) and compound 2 (1.3g, 6mmol) were added into a sealed tube. After the addition was complete, the sealed tube was taken out of the glove box and reacted at 130° C. for 20 h. After the reaction was completed, the reaction liquid was returned to room temperature, extracted with DCM and saturated ammonium chloride, and the extraction was repeated three times and the organic phase was collected. The organic phase was washed with anhydrous MgSO 4 Dry, filter with Celite, and spin dry. Separation by column chromatography (PE:EA=10:1, R f =0.32), to obtain ...
Embodiment 3
[0072] This example presents the application of the carbon nanotube structure compound as a fluorescent material, and the carbon nanotube structure compound obtained in Example 1 is used as the carbon nanotube structure compound in this example.
[0073] The "windmill-like" carbon nanotube structure compound obtained in Example 1 has carried out the measurement of the fluorescence emission spectrum, and found that it has better spectroscopic properties, and the comparison diagram of its dichloromethane solution under ultraviolet light at 254nm and 365nm is as follows figure 2 shown. Such as figure 1 shown. It can be seen from its fluorescence emission spectrum that its peaks are all in the blue light region. As the polarity of the solvent changes, the position of the emission peak remains unchanged, but the emission intensity changes. Among them, the emission intensity is the largest in dichloromethane, and the emission intensity is the smallest in n-hexane. It has broad a...
