Mechanical properties. a The Young’s modulus, E, as a function of indentation depth for two samples of (ZIF-4-Co)0.5(ZIF-62)0.5. Error bars represent the standard deviation of 26 measurements for sample 1 (blue) and 8 for sample 2 (red). Inset—optical images of the two samples. Scale bars are 20 μm. b Load–displacement curves for both samples and c Ashby-style plot of existing alloys, blends and glasses, with the materials here placed into context. Data for ZIF-4 was taken from previous work27. Different shadings represent broad material classes
