Abstract
3,4-Dimethylpyrrole-2-aldehyde was converted into methano (1), ethano (2) and 1,3-propano N-10,N-11-bridged dipyrrinones. At room temperatur e in cyclohexane the large fluorescence quantum yield associated with 1 (phi(F) similar or equal to 0.81) falls off significantly with incre asing bridge length (2:phi(F)=0.26, 3:phi(F)=0.0012).
