Add to ORKGMelanin is a natural pigment mainly responsible for theprotection of skin and eyes from UV damage. 5,6- dihydroxyindole-2 carboxylic acid (DHICA) is a key melanin building block.We have investigated the excited state dynamics of DHICA aswell as its derivatives and oligomeric units using ultrafastfluorescence spectroscopy. Time-resolved fluorescence experimentsrevealed single exponential decays of the excited state forall the molecules studied.The key observation was a sizedependent deactivation of the excited state.</p
