Nucleobase-grafted supramolecular polymers for tuning the surface properties

Abstract

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 physical cross-linking. In addition, they can self-organize to alter material behavior with light, switching both optical and thermal properties. Remarkable changes in the surface morphology and the contact angle with water were also observed.
