Reaction of chiral 2,2’-biamino-1,1’-binaphthalene (R or 5) with monosubstituted porphyrin 1b and 2b-c afforded novel chiral diporphyrins 3a-c and 4a-c. Their dimetal complexes [(M)2DiPor] have also been prepared. Both structures have been identified by MS, IR, UV-visible, 1H NMR spectra and elemental analysis. These novel chiral compounds show very high optical activities.
