The introduction of hydroxy group to the 3- or 5-position of 4,4-difluoro-4-bora-3aAa-diazaindacene （BODIPY） results in unexpected tautomerization to BDPONa with interesting structural and photophysical properties. The core of BDPONa is an anion with sodium cation as counter-ion. BDPONa displays strong fluorescence in organic solvents.
