Abstract
Melanin is a natural pigment mainly responsible for the
protection 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 as
well as its derivatives and oligomeric units using ultrafast
fluorescence spectroscopy. Time-resolved fluorescence experiments
revealed single exponential decays of the excited state for
all the molecules studied.The key observation was a size
dependent deactivation of the excited state.
