ABSTRACT
This chapter summarizes the molecular scaffolds for the creation of the β-sheet and turn structures of attached peptides and the chirality organization of π-conjugated Polyanilines. The chirality organization of the phenylenediamine derivative 44red-l bearing the l-Pro-OMe moieties through the intramolecular hydrogen bonding is supported by the appearance of induced circular dichroism at the absorbance region of the л-conjugated moiety. The introduction of the amino acid moieties into the phenylenediamine derivative at 2,3-positions results in a syn-conformation of the π-conjugated moiety. An optically active copolyaniline, poly(aniline-co-o-toluidine), is prepared by chemical polymerization with (1S)-(+)- or (1R)-(–)-10-camphorsulfonic acid as the chiral inductor in organic media. The utilization of self-assembling properties of amino acids, which possess chiral centers and hydrogen bonding sites, is considered to be a powerful tool for structurally defined molecular assemblies. Configuration and sequence of amino acids play an important role in construction of chirality-organized bioinspired systems. The utilization of a molecular template is a convenient strategy to induce chirality-organized structures.
