Poly foldamers

Since a comprehensive review [28] was completed in 2001, every effort will be made not to duplicate this tome. Additionally, 3-peptides have been the subject of several reviews and will be mentioned more briefly than they warrant. Other recent reviews have covered oligoarylamides [29], a brief review of foldamers in general [30], and an article [31] focusing on the secondary structure aspect of foldamers. We will not include polymers like polyphenyl acetylene derivatives, polyisocyanides, and poly(trityl methacrylates) in which the conformations are dominated by nearest neighbor steric interactions, although these macromolecules represent very interesting systems that seem to adopt a limited number of the available conformations in solution [32-35].
