Dear researchers,
I am looking for approaches to covalently bond amine-functionalized hexagonal boron nitride nanosheets with graphene oxide. Commonly, graphene oxide has several carboxylic acid groups at the edges and these groups can be further connected to other amine compounds through amidation processes. However, these carboxylic groups of graphene are weakly reactive, thus, current advances propose to transform carboxylic into more reactive acyl chloride. My question is:
Whether the amine group in amine-functionalized hexagonal boron nitride nanosheets can react directly to carboxylic acid/acyl chloride in graphene oxide or not?
Thank you very much!
Best Regards,
Sang Pham.
Hi,
Acyl chloride improve the reactivity of the -COOH group. However, only -COOH can also reactive to the -NH2 group but the amide bond formation will be very less in that case. Another option is to improve the yield % by incorporating some water soluble coupling reagent.
Thanks
Best,
Suman
Hi Suman,
Thanks for your answer! It will be great if you can suggest to me some water-soluble coupling reagents.
Another thing is do you have any idea of the reactivity of -NH2 group attached on h-BN sheet? It is surprising for me that this information has received less research compared to COOH and OH in graphene.
Best,
Sang Pham.
