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.
