Description
A one-pot synthetic method was established for the preparation of 2,5-disubstituted-1,3a,6a-triazapentalenes. The fluorescence observation of the synthetic 2,5-disubstituted-1,3a,6a-triazapentalenes revealed that the introduction of a substituent at the C5 position allowed a substantial change in the fluorescence quantum yield with little effect on the fluorescence wavelength.
