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