In biological systems Chirality is important property from small molecules to macromolecules. The construction of homochiral coordination supramolecules in crystal and helical delivers the connection of molecular and macromolecular chirality. Complexity and properties in the presence of cadmium ion and bpe auxiliary ligand for bio-molecular guanosine-5- monophosphate disodium salt (GMP) was studied. The two Complexes 1 and 2 have been investigated the impact of auxiliary ligand bpe, hydroxy group on the sugar motif and pH for coordination of GMP ligands. The interaction of mixed ligands for growth and advancement of chiral complexes was controlled by the alteration of pH values for coordination of guanosine-5-monophosphate nucleotide with cadmium Cd (II) metal. The chirality of complexes 1 and 2 was studied with solid circular dichroism (CD) spectroscopy, including supramolecular chirality and extended auxiliary ligand (EAC) combining with the crystal structure analysis. The various hydrogen bonding and auxiliary ligand are the special means of transporting chirality from isolated molecules to dynamic supramolecular three-dimensional designs of GMP nucleotide crystals. The research results will be benefit to the controlling supramolecular assembly with well-defined structure and properties.

“…The negative peak at 245 nm is attributed to π-π* transitions of the aryl group in 3, and the positive peak at 319 nm is attributed to intramolecular charge transition and the formation of the helical structure. [73][74][75][76] Chiral behavior in the liquid state was also explored, but no obvious chiral signal was observed (Fig. 6b).…”

Self-assembly is the most powerful force for creating ordered supramolecular architectures from simple components under mild conditions. π···π stacking interactions have been widely explored in modern supramolecular chemistry as an attractive reversible noncovalent tool for the nondestructive fabrication of materials for different applications. Here, we report on the self-assembly of cytidine 5’-monophosphate (CMP) nucleotide and copper metal ions for the preparation of a rare nanoporous supramolecular metal-organic framework in water. π···π stacking interactions involving the aromatic groups of the ancillary 2,2’-bipyridine (bipy) ligands drive the self-assemblies of hexameric pseudo-amphiphilic [Cu6(bipy)6(CMP)2(µ-O)Br4]2+ units. Owing to the supramolecular geometric matching between the aromatic tails, a nanoporous crystalline phase with hydrophobic and hydrophilic chiral pores of 1.2 and 0.8 nanometers, respectively, was successfully synthesized. The encoded chiral information, contained on the enantiopure building blocks, is transferred to the final supramolecular structure, assembled in the very unusual topology 8T6. These kinds of materials, owing to chiral channels with chiral active sites from ribose moieties, where the enantioselective recognition can occur, are, in principle, good candidates to carry out efficient separation of enantiomers, better than traditional inorganic and organic porous materials.
