Syntheses of fused heterobicyclic systems containing 1,2,4-triazolopyridinone moieties were accomplished by heterocyclization of 1,6-diamino-2-oxo-4-phenyl-1,2-dihydropyridine-3,5-dicarbonitriles and ninhydrin in ethanol and in the presence of boric acid as a catalyst in 30?min at room temperature. All compounds have been screened for their photophysical properties. Results showed that all compounds exhibit near infrared emissions at 876?nm.

Annelation reaction between pentafluoropyridine and diaminodihydro substituted pyridine derivatives gave dipyrido[1,2-b:3′,4′-e][1,2,4]triazine systems as major products arising from the initial nucleophilic substitution of more nucleophilic N-amino group
