Metal–Biomolecule Frameworks B. Joarder, A. K. Chaudhari, S. S. Nagarkar, B. Manna, S. K. Ghosh* .................. &&&&—&&&& Amino Acid Based Dynamic Metal– Biomolecule Frameworks On the move : Two isostructural homo- chiral Cu II coordination frameworks based on amino acid (d- and l-PGA) were synthesized (see figure). Dynamic behavior by solid-state structural trans- formation in single crystal-to-single crystal fashion was demonstrated. The extent of structural dynamism was shown by guest inclusion studies. Reversible sol-gel formation and anion-tuning morphology of the com- pounds is also discussed. Chem. Eur. J. 2013, 00,0–0 2013 Wiley-VCH Verlag GmbH & Co.
