Layered compounds generate host-guest composites with emergent properties. Organic layered materials have intercalation and dynamic natures originating from the layered structure and the organic compound, respectively. Our intention here is tuning the dynamic properties by intercalation. Here, we report on organic layered composites with tunable stimuli-responsive colorchange properties by intercalation. A diacetylene monomer with a layered crystal structure accommodated the guest organic amines through intercalation. Subsequent polymerization formed the layered composites, consisting of the host polydiacetylene and the guest amines. The mechano-responsive colorchange properties were systematically controlled by sorts of intercalated amines. In general, it is not easy to tune responsivity to mechanical stimuli, such as shear stress. The tunable mechano-responsive color-change properties realize memory and visualization of the accumulated shear stress, such as the number of rubbings. The intercalation approach shows potential for the development of tunable stimuli-responsive materials and their wide range of applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
