Functionalization of (R)- and (S)-polycarbodiimides of different composition bearing active ethynyl groups was accomplished thru standard CuAAC �click�-chemistry protocol leading to cross-linked products. Morphology characterization (SEM, TMAFM) revealed the formation of fiber-like aggregates assembled from the bundles of individual helices. It seemed likely that behavior observed is a result of extensive hydrophobic interactions of the singular polycarbodiimide chains. Model proposed is originated from the analysis of single crystal X-ray data of multiple aliphatic ureas showed interdigitation pattern in a crystal lattice that possibly mimics the organization of macromolecules in fibrous aggregated morphologies .
