organic compounds
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.
organic compounds
In the title compound, C44H38N4·2CHCl3, the porphine (CP) is a soluble precursor of metal-free porphyrin which exhibits an excellent field-effect transistor characteristic. The CP skeleton is entirely flat and characterized by crystallographic Ci symmetry. In the present geometrical isomer, the C-C single-bond linkages of the four peripheries are arranged in an above-above-below-below manner with respect to the CP skeleton.
