WebNov 1, 2001 · It is assumed that without such interaction, the polymer backbone has a Kuhn length of λ0-1 and each side chain consisting of n (»1) bonds is Gaussian. WebPhg4 self-assembly into stable β-sheet ladders was facilitated by π-staking of aromatic sidechains alongside hydrogen bonding between backbone amides along the nanofibre axis. The contribution of these non-covalent interactions in stabilising self-assembly was predicted by in silico modelling using molecular dynamics simulations and semi-empirical …
