Abstract

Bright yellow N,N'‐carbonyl‐bridged dipyrrinones (substituted 3__H__,5__H__‐dipyrrolo[1,2‐c:2′,1′‐f]pyrimidine‐3,5‐diones) were synthesized by reaction of the parent dipyrrinone with carbonyldiimidazole. Their solutions in organic solvents fluoresced strongly, with fluorescent quantum yields (ϕ~F~)0.32‐0.92.
