- 2,2'-Dipyrromethene, often called just dipyrromethene or dipyrrin, is a chemical compound with formula C9H8N2 whose skeleton can be described as two pyrrole rings C5N connected by a methyne bridge =CH– through their nitrogen-adjacent (position-2) carbons; the remaining bonds being satisfied by hydrogen atoms. It is an unstable compound that is readily attacked by nucleophilic compounds above −40 °C. 2,2'-Dipyrromethene and its more stable and easily prepared derivatives—formally obtained by replacing one or more hydrogen atoms by other functional groups—are important precursors for the family of BODIPY fluorescent dies. The derivatives include salts of the dipyrrinato anion C9H7N–2 and of the cation C9H9N+2. (en)
