N2 - 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 color-change 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 color-change 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.
