The variety and complexity of DNA-based structures make them attractive candidates for nanotechnol., yet insufficient stability and mech. rigidity, compared to polyamide-based mols., limit their application. Here, we combine the advantages of polyamide materials and the structural patterns inspired by nucleic-acids to generate a mech. rigid fluorenylmethyloxycarbonyl (Fmoc)-guanine peptide nucleic acid (PNA) conjugate with diverse morphol. and photoluminescent properties. The assembly possesses a unique at. structure, with each guanine head of one mol. hydrogen bonded to the Fmoc carbonyl tail of another mol., generating a non-planar cyclic quartet arrangement. This structure exhibits an average stiffness of 69.6 ± 6.8 N m-1 and Young’s modulus of 17.8 ± 2.5 GPa, higher than any previously reported nucleic acid derived structure. This data suggests that the unique cation-free “basket” formed by the Fmoc-G-PNA conjugate can serve as an attractive component for the design of new materials based on PNA self-assembly for nanotechnol. applications.
