| Overview | in recent years, fluorescent carbon nanomaterials have attracted much attention and made rapid development because of their environmental friendliness. As a new member of the family of fluorescent carbon nanomaterials, carbon dots have attracted the attention of many researchers since it was first reported in 2004. Compared with traditional organic small molecule dyes, carbon dots have good optical stability, biocompatibility and low cytotoxicity, so they have a wide range of applications in the field of life analysis. 1,2, 4-triaminobenzene hydrochloride is a relatively simple structure of aromatic ternary Amine, relative to triaminopyridine is easier to synthesize and realize industrialization, to a certain extent can replace TAP and 2, 5-dihydroxyterephthalic acid (DHTA) was polymerized. |
| Application | 1,2, 4-triaminobenzene hydrochloride as a co-doping reagent, aconitic acid-based fluorescent carbon nanomaterials with high quantum yield can be prepared to control the emission wavelength. |
| preparation | (1) with M-dichlorobenzene as raw material, in the mixed acid system of concentrated sulfuric acid and fuming nitric acid, 1, 3-dichloro-4, 6-dinitrobenzene was obtained by high-temperature nitration;(2) 1, 3-dichloro-4, 6-dinitrobenzene was placed in a high-pressure reaction kettle in the presence of ammonia, aminolysis reaction to obtain 4, 6-dinitro -1, 3-phenylenediamine by heating to 145~150 deg C;(3) 4, 6-dinitro -1, 3-phenylenediamine, the oxygen-free distilled water and the Palladium-carbon catalyst were placed in a hydrogenation autoclave, and after catalytic hydrogenation reaction in a hydrogen atmosphere of 1-1.5MPa and 85 ℃, the catalyst was removed by hot filtration under the protection of nitrogen to obtain 1,2, 4-triaminobenzene hydrochloride solution; (4) take the 1,2,4, 5-tetraaminobenzene solution obtained in step (3) and add concentrated hydrochloric acid, cool to room temperature and filter under nitrogen protection, the filter cake was dried in a vacuum dryer at 40 ° C. To obtain 1,2, 4-triaminobenzene hydrochloride. The molar ratio of M-dichlorobenzene to fuming nitric acid in step (1) is 2.2:1, and the mass ratio of concentrated sulfuric acid to fuming nitric acid is 3:8-10, the dropping temperature was -5 to 0 ℃, and the nitrification temperature was 100 to 104 ℃. The aminolysis reaction time in step (2) is 3.5-4H, and the molar ratio of 1, 3-dichloro-4, 6-dinitrobenzene to ammonia is 1:(10-10) ~ 14). The anaerobic distilled water in step (3) is nitrogen purified distilled water, and the catalytic hydrogenation reaction time is 3-4H; 4, 6-dinitro-1, 3-phenylenediamine, the mass ratio of the Palladium-carbon catalyst to the oxygen-free distilled water was 1:0.05:10. The volume ratio of the 1,2, 4-triaminobenzene hydrochloric acid solution to the concentrated hydrochloric acid in the step (4) is 1:0.2-0.3. The route of the entire reaction is as follows: |
