Abstract

Steady-state and time-resolved photoluminescence (PL) spectra of
natural and synthetic melanin, as well as melanin composites with
surfactant, sodium dodecylbenzenesulfonate, and polymethine dye,
astraphloxin, have been studied. The melanin molecules having differently
charged peripheral groups with terminal O atoms and OH
groups mixed with the negatively charged surfactant or positively
charged astraphloxin dye feature new PL spectral bands. The kinetics
of PL and time-resolved emission spectra for the melanin and the
composites were also investigated and discussed in terms of intermolecular
complexation, nano-aggregation and formation of chargetransfer
states. The studies are aiming to understand the electronic
properties of various melanins, particularly natural ones.
