| Abstract |
5,6-dihydroxyindole(DHI) and 5,6-dihydroxyindole-2-carboxylic acid(DHICA) are two canonical monomers of melanin polymers. DHICA a carboxyl group is attached to the carbon Ⅱ position of DHI. Synthetic DHICA eumelanin is a more efficient free-radical scavenger than DHI eumelanin, and shows atypical optical, paramagnetic, and aggregation properties in the solid state, which is due to the interrupted π-electron network in its supramolecular structure. To investigate the effect of carboxyl groups on the materials properties of supramolecular melanin derivatives, we chemically synthesized DHICA and its derivatives to examine their structural and functional characteristics. |
