In the title compound, C44H38N4·3C7H8, 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 D2h), but is slightly deformed, as characterized by crystallographic Ci symmetry. The geometric isomer of CP could not be identified due to orientational disorder.
