| titleOfInvention | The preparation method of dication carbazole fluorescent probe |
| abstract | The present invention provides a kind of preparation method of dication carbazole fluorescent probe, the method step is under the conditions of magnetic agitation, N alkyl 3,6 dialdehyde-based carbazole, the benzindole salt of 2 3mmol, the mixed solvent of 20 50ml and the inorganic salt catalyst of 1mmol is sequentially added in reaction bulb；React 12 24 hours at 20 25 DEG C；Reaction finishes, and reactant liquor sucking filtration obtains crude product；Crude product cleaning solvent is followed by stirring and washing 13 times, then sucking filtration, is dried to obtain dication carbazole compound.Beneficial effect is that solvent is cheap and easy to get, and catalyst is with low cost, and preparation method is simple to operate using saturated fatty alcohol and aqueous mixtures as solvent, and high conversion rate carries out separating and expensive palladium acetate catalyst without using column chromatography, reduces environmental pollution.The product that the preparation method of dication carbazole fluorescent probe obtains adopts efficient liquid phase detection content to be more than 96%. |
