Abstract
Reactions of chiral 2,2′-biamino-1,1′-binaphthalene (R or S) with mono-substituted porphyrin 1a, 2b-c afforded novel chiral diporphyrins 3a-c and 4a-c which possess different linkers between the binaphthalene and porphyrin ring. Their structures have been identified by MS, IR, UV-visible and 1H NMR spectra, and elemental analysis.
