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) (Lambda-1) and {[Ni(f-(RR)-L)](2)(d-pends) (ClO4)(2)}(n) (Delta-1). The frameworks possess ID tubular pores and opposite right/left-handed helical porous surfaces (L = 5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane; pends(2-) = penicillaminedisulfide anion).
