• Here, we report the synthesis of a truncated cone‐shaped triangular porphyrinic macrocycle, P3L3, via a single step imine condensation of a cis‐diaminophenylporphyrin and a bent dialdehyde‐based linker as building units. X‐ray diffraction analysis reveals that the truncated cone‐shaped P3L3 molecules are stacked on top of each other by π⋯π and CH⋯π interactions, to form 1.7 nm wide hollow columns in the solid state. The formation of the triangular macrocycle is corroborated by quantum chemical calculations. The permanent porosity of the P3L3 crystals is demonstrated by several gas sorption experiments and powder X‐ray diffraction analysis. One‐pot imine condensation of a cis‐diaminophenylporphyrin and a bent dialdehyde‐based linker as building units produce a shape‐persistent truncated cone‐shaped macrocycle, which self‐assembles into a 1D porous material with 1.7 nm wide hollow channels in the solid state.
