Chiral carbon dots derived from guanosine 5′-monophosphate form supramolecular hydrogels

Abstract

Guanosine 5′-monophosphate, (5′-GMP), is a self-assembling natural nucleotide that has unique potential to form ordered supramolecular structures. We herein describe an intriguing property of Na2(5′-GMP) to form blue emitting chiral carbon dots (G-dots) that exhibit excitation dependent down-conversion and up-conversion fluorescence signature and self-assemble to form fluorescent hydrogels.
