Using a light switch to turn chemical reactions on and off

My latest news article in Chemistry World is about a light switch, not a lightswitch, that can control chemical reactivity. The PR team at the research centre involved have put together a nice video showing the experiments involved, watch for the lasers and dry ice, I’m pretty sure, #RealTime doesn’t involve Pink Floyd stage effects…but, it does look dramatic nevertheless.
