Taming of a Shape-Shifter Molecule
Isomer convergence of a permanently fluctuating coordination cage.
Shape-shifter molecules are in never-ending motion. Their structure fluctuates because the carbon bonds that hold them together constantly break up and form again. Researchers have now found a way to “tame” a shape-shifter molecule called bullvalene. In the journal Angewandte Chemie, they report that integrating the molecule into a coordination cage enables its shape-shifting behavior to be restricted through molecular recognition. Such form capturing could play a role in responsive materials.
Chemical bonds between carbon atoms can be strong, as in the hydrocarbon gas ethane, or strained, as in triangular cyclopropane, or they can fluctuate between both kinds, such as in the organic hydrocarbon compound bullvalene.
