摘要
(Figure Presented) Counterintuitively improved photoswitching properties of bridged azobenzene compared to the unbridged counterpart (see picture) were demonstrated recently. Mechanistic insights obtained from nonadiabatic ab initio molecular dynamics reveal that the bridge suitably preorients the phenyl rings and thus enhances the E→Z quantum yield and shortens the lifetime of the first excited state. © 2010 Wiley-VCH Verlag GmbH & Co.
