The photochemistry of 9-diazo-1,8-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 n-?* band, no diazirine is formed, but triplet 18FL is formed directly along with the singlet, and the quantum yield for reaction is reduced ca. 12-fold when compared with the UV photolysis.
