A porous hydrogen‐bonded organic framework (HOF) composed of triaxially woven chicken wires of tetra‐topic carboxylic acid is reported. This exotic framework is provided by disproportional conformation of the phenylene rings in the peripheral biphenyl arms. The activated HOF exhibits thermal stability up to 220 °C and Brunauer–Emmett–Teller surface area of 555 m 2 g −1 . The HOF shows mechanochromic behavior in terms of fluorescence color and quantum efficiency. More information can be found in the Full Paper by I. Hisaki et al. on page 17056.
