Nucleobase-grafted supramolecular polymers for tuning the surface properties was written by Lin, I.-Hong;Cheng, Chih-Chia;Li, Ke-Fong;Chen, Jem-Kun;Chiu, Chih-Wei;Chang, Feng-Chih. And the article was included in Polymer Chemistry in 2014.Formula: C7H9N3O This article mentions the following:
Nucleobase-grafted polycaprolactone has been prepared which exhibits amorphous nature, rapid photoresponse and controlled surface properties in the solid state owing to the formation of uracil-diamidopyridine (U-DAP) pairs by induced phys. crosslinking. In addition, they can self-organize to alter material behavior with light, switching both optical and thermal properties. Remarkable changes in the surface morphol. and the contact angle with water were also observed In the experiment, the researchers used many compounds, for example, N-(6-Aminopyridin-2-yl)acetamide (cas: 1075-62-3Formula: C7H9N3O).
N-(6-Aminopyridin-2-yl)acetamide (cas: 1075-62-3) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the π-bonding aromatic system using its unhybridized p orbital. The lone pair is in an sp2 orbital, projecting outward from the ring in the same plane as the σ bonds. Halopyridines are particularly attractive synthetic building blocks in a variety of cross-coupling methods, including the Suzuki-Miyaura cross-coupling reaction.Formula: C7H9N3O
