摘要：

(Figure Presented) Know where to fold 'em: A foldamer exhibiting a light-induced helix-coil transition (see scheme) can be constructed by introducing a photochromic azobenzene moiety (red) into the center of an amphiphilic phenylene ethynylene backbone (blue). This system gives insight into folding and unfolding mechanisms and promises applications in photoresponsive (bio)materials and smart" delivery devices based on photoresponsive dynamic receptors. © 2006 Wiley-VCH Verlag GmbH & Co.
