English Dimensionality plays an important role in the charge transport properties of organic semiconductors. Although three-dimensional semiconductors, such as Si, are common in inorganic materials, imparting electrical conductivity to covalent three-dimensional organic polymers is challenging. Now, the synthesis of a three-dimensional π-conjugated porous organic polymer (3D p-POP) using catalyst-free Diels-Alder cycloaddition polymerization followed by acid-promoted aromatization is presented. With a surface area of 801 m2  g-1 , full conjugation throughout the carbon backbone, and an electrical conductivity of 6(2)×10-4  S cm-1 upon treatment with I2 vapor, the 3D p-POP is the first member of a new class of permanently porous 3D organic semiconductors.
