Late at night in Princeton's Frick Chemistry Laboratory, blue LED lights work overtime to catalyze new chemical reactions.

Bright future: Unlocking the potential of light

The leader in the emerging field of using light to perform feats of chemistry is David MacMillan, who arrived in Princeton's chemistry department in 2006. He was intrigued by the potential for using light to coax new chemical reactions. Like most chemists, he’d spent years learning the rules that govern the interactions of elements such as carbon, oxygen and hydrogen, and then using those rules to fashion new molecules. Could light help change these rules and catalyze reactions that have resisted previous attempts at manipulation?
