THE EXTENSION OF CONJUGATED SYSTEM IN PYRIDYL-SUBSTITUTED MONOAZATRIPHENYLENES FOR THE TUNING OF PHOTOPHYSICAL PROPERTIES

We propose a method for the synthesis of diaryl-substituted pyridylmonoazatriphenylenes by the heterocyclization reaction of dihalosubstituted phenanthrenequinones with pyridine-2-carboxylic acid amidrazone, followed by aza-Diels–Alder reaction and Suzuki cross coupling. The obtained compounds showed more promising photophysical properties, compared to non-arylated analogs. How to Cite Kopchuk, D. S.; Khasanov, A. F.; Kovalev, I. S.; Zyryanov, G. V.; Kim, G.
