"Increasing the efficiency of the ring-opening reaction of photochromic indolylfulgides by optical pre-excitation" T. Brust, S. Draxler, J. Eicher, W.J. Lees, K. Rück-Braun, W. Zinth, M. BraunChemical Physics Letters 489 (2010) 175–180 Abstract: For three indolylfulgides the quantum efficiency of the ring-opening reaction upon preexcitation is investigated in a multipulse experiment. The quantum efficiency grows by factor of up to 3.4, when the pre-excitation pulse immediately precedes the excitation process. The change in quantum efficiency after pre-excitation is discussed as a function of reaction time, steady-state quantum efficiency and energetic barriers in the excited electronic state. The observed differences can be explained by the molecular properties of the investigated indolylfulgides.
