The photochemistry of 9-diazo-l,8-diazafluorene (18DAF) depends on the wavelength of the irradiating light. When photolyzed at ca. 310 nm, into a -* absorption band, excited 18DAF rearranges to a diazirine and loses nitrogen to form the carbene 1,8-diazafluorenylidene (18FL) exclusively in the singlet state. However, when 18DAF is photolyzed at ca. 420 nm, into the -* band, no diazirine is formed, but triplet 18FL is formed directly along (4) Turro, N.
