About the Project
In this programme we will investigate the interaction of light with a number of synthetic molecular motors and switches. In many case the absorbed light energy is converted into molecular motion by means of an excited state reaction, often a cis to trans isomerization reaction. These occur on the timescale of picoseconds or faster. We will investigate the nature of these reactions using a number of ultrafast laser experiments designed in our group. These experiments will probe the rate of the reactions and the structural evolution of the molecules during the switching process. The overall objective is to build up a picture of the features that effect the reaction and so enable the design of improved switches.
