摘要

As part of a program designed to elucidate the excited state properties of key eumelanin building blocks, we report herein a study of 5, 6-dihydroxyindole (DHI) in phosphate buffer at pH 3 and pH 7 using femtosecond transient absorption spectroscopy. The transient absorption changes following excitation at 266 nm were used to directly monitor relaxation of the excited states. It was found that the initially generated excited state of DHI, exhibiting ...
