## Abstract To develop a novel π‐conjugated molecule‐based supramolecular assembly, we designed and synthesized trisdehydrotribenzo[12]annulene ([12]DBA) derivative **2** with three carboxyl groups at the periphery. Recrystallization of **2** from DMSO gave a crystal of the solvate **2⋅**3 DMSO. Cr
