Construction of Two 3D Homochiral Frameworks with 1D Chiral Pores via Chiral Recognition

The reactions of a pair of enantiomers of macrocyclic nickel(II) complexes with racemic penicillamine generated two 3D hydrogen-bonded homochiral frameworks of {[Ni(f-(SS)-L)]2(l-pends)(ClO4)2}n (Λ-1) and {[Ni(f-(RR)-L)]2(d-pends) (ClO4)2}n (Δ-1). The frameworks possess 1D tubular pores and opposite right/left-handed helical porous surfaces (L = 5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane; pends2− = penicillaminedisulfide anion).
