A paper published at 2005 discussed the interaction between terpyridine and CNT.
That triggered me to think what if we put terpyridine on the top of graphene?
Could Terpy serve as a nanoparticle template for graphene?
To test this idea, I've tried to immerse the graphene-contained silicon chip into the 50 mM ethanolic solution for 1 hr just like the way they do. But turns out, the outcome is far beyond what I expected.
The Raman spectroscopy results showed that the peaks does not change at all, neither does the electrical properties.
Furthermore, I also tried to immerse the Terpy-modified samples into metal ions solution for the nanoparticle formation test. And I scanned the surface with AFM and tried to find the nanoparticles that should be formed on the surface of graphene. But the result was not as good as I anticipated. Only little amount of nanoparticles were formed and located everywhere without spatial selectivity.
The paper claimed that the terpyridine would associate CNT through nitrogen-mediated interactions instead of the π-π interactions. But if this statement is true, why it can not be applied in the case of graphene?
The possible reason is that the curvature of CNT is the crucial character for the interaction between Terpy and CNT.
