•  Ultrafast and transient spectroscopy study of ring closing/opening reactions of diarylethene photochromic molecules in solution and on the surface of gold nanoparticles as the function of the nature of functional groups

Description

Ultrafast pump-probe spectroscopy is a powerful tool to study the switching dynamics of diarylethene photochromic molecules at the picosecond and sub-picosecond time scales. This method allows to monitor the ultrafast processes that occur during the ring-closing reaction: redistribution of electronic density, molecular geometry changes, and π-π conjugation at photochromic core. The aim of the project is to understand the influence of the nature of side-chain groups on a ring-closing reaction of diarylethene molecules.
