[0030] A method for synthesizing amphiphilic light-emitting molecules with aggregation-induced light-emitting characteristics of the present invention comprises the following steps: under a nitrogen atmosphere, heat and reflux polyetheramine as a reaction initiator and a grafting agent to obtain a brown Liquid product, the product is cooled to room temperature, washed with an organic solvent, filtered, and dried. The final product is brown waxy solid or syrup.
[0031] A method for synthesizing amphiphilic light-emitting molecules with aggregation-induced light-emitting properties of the present invention, wherein the structural formula of the reaction initiator polyetheramine is:
[0032] or ;
[0033]Wherein, X and Z are integers from 0 to 100, and Y is an integer from 5 to 500.
[0034] The invention relates to a method for synthesizing amphiphilic light-emitting molecules with aggregation-induced light-emitting properties, wherein the grafting agent is any one of carb...
Embodiment 1
[0045] Example 1: Synthesis of AFPEA-18 Luminescent Molecules
[0046] Synthesis method: Weigh a certain amount of JeffamineED2003 and stearic acid into a 50mL three-necked round bottom flask, the molar ratio of JeffamineED2003 to stearic acid is 1:2~1:2.2. Under the protection of nitrogen, heat to 160-200°C with magnetic stirring, react for 4-8 hours (detect the reaction time by TLC), stop heating, and obtain a brown liquid product. After the product was cooled to room temperature, it was washed with petroleum ether, filtered, and dried. The final product was a brown waxy solid. use 1 The structure of the product was characterized by HNMR, which confirmed that the product was compound AFPEA-18. 1 HNMR (500MHz, CDCl 3 )δ0.83(t,6H,J=5.6Hz),1.04~1.12(m,21H),1.20~1.23(m,56H),1.56(m,4H),2.09(t,4H,J=6.12Hz ), 3.59(m,170H).
Embodiment 2
[0047] Example 2: Synthesis of AFPEA-16 Luminescent Molecules
[0048] Synthetic method: similar to the synthetic method of Example 1, the difference is that the grafting agent is palmitic acid, and the product is a brown waxy solid. use 1 The structure of the product was characterized by HNMR, which confirmed that the product was compound AFPEA-16. 1 HNMR (500MHz, CDCl 3 )δ0.88(t,6H,J=6.75Hz),1.09~1.18(m,21H),1.25~1.28(m,48H),1.61(m,4H),2.14(t,4H,J=8.45Hz ),3.60~3.69(m,170H).
