Chemists have developed enough molecular switches to populate a molecular hardware store. Yet it’s rare for switching on the atomic scale to translate into an effect at the macroscopic level. Now, Xin Su, Ivan Aprahamian, and colleagues at Dartmouth College have developed a molecular switch that can change a liquid crystal’s color in response to pH (Angew. Chem. Int. Ed. 2013, DOI: . . .
