Shaping of a Conformationally Flexible Molecular Structure for Spectroscopy

Chaperones for wild molecules: A molecule's conformational flexibility can be eliminated by enclosing it with a macrocyclic mold as a [2]rotaxane (see picture) that forces it into a specific shape. After rapid cooling, the mold is removed with a laser pulse. Through this process, the molded mol...

Description
Summary:Chaperones for wild molecules: A molecule's conformational flexibility can be eliminated by enclosing it with a macrocyclic mold as a [2]rotaxane (see picture) that forces it into a specific shape. After rapid cooling, the mold is removed with a laser pulse. Through this process, the molded molecule becomes a suitable candidate for high‐resolution electronic excitation spectroscopy.
