Artist’s Dye Fading: Summary

This summer has seen a lot of frustration but also a lot of progress. The main focus of my work has been trying to figure out photo-physical behavior of purpurin, purpurin lake, and alizarin in different conditions in order to fill in the blanks from the previously accomplished single molecule studies. This new data allows us to more accurately interpret the single molecule data and gives us parameters for the Monte Carlo simulations. The single molecule data only tells us the relative behavior of the molecules by showing us a portion of the on and off lifetimes and the functions they are characterized by. In order for this data to have a physical interpretation we need to understand what sort of photo physical processes are happening which is where this summer’s research comes into play.
