The Excited State Behavior of Aminostilbenes. A New Example of the Meta Effect

摘要

Our results suggest that long fluorescence lifetimes and high fluorescence quantum yields may be a general characteristic of m-amino-substituted trans-1, 2- diarylolefins. Preliminary results indicate that a m-amino effect is also observed for cis-1, 2-diarylolefins. As such, the m-amino effect may prove of value in the design of new fluorescent materials.
