title: Photoresponsive peptoid oligomers bearing azobenzene side chains.
abstract: 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.
