Discrimination Between Alkyl and Aryl Substituents of Chiral Monoamines by M-phthalic Diamide-linked Zinc Bisporphyrinates

m-Phthalic diamide-linked zinc bisporphyrinates have been developed as chirality probes for monoamines. They are capable of determining the absolute configuration of monoamines and distinguishing between alkyl and aryl substituents of chiral monoamines. Our studies suggest that steric interactions play critical roles in the molecular recognition process.
