Abstract: As part of our efforts aimed at developing molecular receptors and peptide conformational templates, we have conducted a research on design, synthesis, and application of structurally modified cyclopeptides. In this paper, we disigned and synthesized three biphenyl-bridged, amino acid-based macrocycles. The investigation of crystallograghic structures reveals that in the solid state, these macrocycles were assembled into twin-tube, 3D network and chain-like supramolecular structures, respectively, in which the C-H...O hydrogen-bonds play important roles. These findings may be helpful for understanding the role of the C-H...O hydrogen bonding in determining crystal packing, molecular recognition, and the structural stability of biological macromolecules.

Key words: Macrocycle compound, Biphenyl, Amino acid, Self-assembly, C-H...O hydrogen bond
