摘要：

We report on the first observation of ultrafast intramolecular charge- and proton-transfer reactions in 4'-dimethylanunoflavonol (DAME) in solution. Upon femtosecond excitation of a non-planar structure of DMAF in apolar medium, the intramolecular charge transfer (ICT) does not occur, and a slow (2 ps) proton motion takes place. However, in polar solvents, the ICT is very fast (100-200 fs) and the produced structure is stabilized that proton motion takes place in few or tens of ps.
