Abstract
1 min read
A rotatable “Rubik's Cube” hydrogel (RC) is macroscopically assembled via controllable dynamic covalent interactions by Jonathan L. Sessler, Ben Zhong Tang, and co-workers in article number 1902365. Overly strong or overly weak interactions between the constituent hydrogel building blocks are avoided as they will preclude formation of the RC or rotation of the constituent blocks. Thus, transient differences in hydrogel binding strength are exploited to create an ensemble endowed with both rotational flexibility and structural integrity.
