Description
Sergi Bujosa, Llorenç Rubert, Carmen Rotger, and Bartolome Soberats explore how designer molecules assemble and switch forms. Ordered structures at tiny scale can build themselves, but clean switches between forms that run backward and forward are rare in known systems. Their molecules, labeled 1 to 3, show rich behavior: four distinct forms, three patterns of interaction, and several controlled changes between forms.
Compound 3, with ethyl spacers, balances among three forms as concentration and temperature shift. Two forms use slipped hydrogen bonds, while a third uses head-to-tail bonds. In the solid state the compounds form columnar liquid crystals. The authors offer these molecules as model systems for balance between forms in future responsive materials.
