A light harvesting Bi-component hydrogel with a riboflavin acceptor

A light harvesting hydrogel, working in a wide range of temperature and pH, of a two component supramolecular complex of melamine and 6,7-dimethoxy-2,4[1H, 3H]-quinazolinedione (donor) with riboflavin (acceptor) shows a gradual quenching and red shift of the acceptor emission peak with increase in its concentration through a co-assembly process.
