In the title compound, C 44 H 38 N 4 ·3C 7 H 8 , the porphine (CP) is a soluble precursor of metal‐free porphyrin which exhibits an excellent field‐effect transistor characteristic. The CP molecule is not entirely flat in its crystal structure ( i.e. not D 2 h ), but is slightly deformed, as characterized by crystallographic C i symmetry. The geometric isomer of CP could not be identified due to orientational disorder.
