文摘

Polypeptides containing azobenzene or spiropyran units attachedto the macromolecules respond to light or dark conditions givingreversible variations of their structure. In this Account we providea short overview of current research in the field and describe themost significant experimental examples of photoresponse effects.They include photoinduced random coil/-helix transitions, helix-sense reversal, photostimulated aggregation/disaggregation processes, and photomechanical effects. These fascinating propertiessuggest that photoresponsive polypeptides may become suitablematerials for designing sensors and devices that can be photomodulated. Findings also demonstrate that it is possible tosynthesize model systems which respond to light similarly tonaturally occurring photoreceptors.
