文摘

Benzil-based -bisimines are implemented as photoswitches for the construction of a speed-regulating molecular device, in which, by application of light, three different states may be addressed, showing distinct frequencies of internal C–C bond rotation, spanning 12 orders of magnitude. Bond rotation barriers were determined experimentally and elucidated by DFT-methods.
