N-Substituted glycine peptoid oligomers were synthesized to incorporate a photoresponsive azobenzene side chain. The ability of this side chain to undergo reversible photoisomerization was established, and the cis- to trans-azobenzene thermal isomerization of this side chain was investigated. Circular dichroism studies indicated that trans- to cis-azobenzene isomerization does not significantly alter the backbone conformation in a series of peptoids thought to have well-defined structures.

D034444	Peptoids	Polymers of N-SUBSTITUTED GLYCINES containing chiral centers at the a-position of their side chains. These oligomers lack HYDROGEN BONDING donors, preventing formation of the usual intrachain hydrogen bonds but can form helices driven by the steric influence of chiral side chains.	Peptoid
