a Crystal structure of PP-I showing the presence of two water molecules in the asymmetric unit. b β-sheet hydrogen bonding in PP-I and one-dimensional water wire. c Pseudoprotein packing in PP-I showing water molecules in the channels. d Crystal structure of PP-II showing two symmetry-independent molecules in the asymmetric unit. e β-sheet hydrogen bonding in the PP-II. f Two dissimilar polymer chains in the PP-II with their phenyl rings placed between the β-strands. g Schematic showing the TAAC reaction in DP-II leading to two conformationally dissimilar polymer chains in PP-II.
