The title compound, 2,6-bis(1-azaazulen-2-yl)pyridine (5), was synthesized by condensation between tropone (6) and 2,6-bis(pyridinioacetyl)pyridinium salt (7) in the presence of ammonium acetate. By slow addition of an acetic acid solution of the pyridinium salt 7 to a mixture of 6 and ammonium acetate the yield of 5 was improved. Physical properties of 5 were investigated. It is worthy to note that upon irradiation 5 shows strong emission in acidic media in contrast to very weak emission in neutral media.

The value of pKb3 could not be obtained because of its spectral change without isosbestic points in strong acidic media.
Emission quantum yields of 5 in CH3CN and EtOH are less than 1 x 10–3%. The yields were determined by comparison with that of anthracene (0.27 in EtOH).
