Abstract

original image

Within the framework: Ionic complexation of diblock copolypeptide poly(γ-benzyl-L-glutamate)-block-poly(L-lysine) (PBLG-b-PLL) with 2′-deoxyguanosine 5′-monophosphate (dGMP, gray) generates a polymeric supramolecular framework solid with self-assembled cages based on two orthogonal shape-persistent motifs: PBLG α helices (blue) and PLL β sheets (red), which in turn are held together by shape-persistent hydrogen-bonded G-ribbons.
