caption_attribution_description: English: Schematic formula of the dipyrromethene molecule, precursor of the BODIPY fluorescent dyes. This formula is the average of the two isomers which have the atoms in the same relative position and differ only in the bond type and direction. The dashed lines represent "half a bond".
context_page_description: 2,2'-Dipyrromethene, often called just dipyrromethene or dipyrrin is a chemical compound with formula C
  ₉H
  ₈N
  ₂ whose skeleton can be described as two pyrrole rings C
  ₅N connected by a methyne bridge =CH– through their nitrogen-adjacent carbons; the remaining bonds being satisfied by hydrogen atoms. It is an unstable compound that is readily attacked by nucleophylic 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 C
  ₉H
  ₇N–
  ₂ and of the cation C
