Abstract
Homochiral coordination polymers have emerged as promising candidates for a range of chirotechnological applications, including asymmetric catalysis and enantioselective separation. The use of ligands derived from naturally occurring l-amino acids is an inexpensive and effective approach for generating a range of homochiral coordination polymers. To investigate the structure-directing effect of the amino acid side chain, seven homochiral Cd(II) frameworks were synthesized using semirigid dicarboxylates composed of l-amino acids appended to terephthalic acid (H2TMXxx, where Xxx = Ala, Val, Phe, Trp, Tyr, and His) and bis(4-pyridyl)ethylene coligands. When Xxx = Val, Tyr, Phe, or Trp, a series..
