Abstract

A convenient synthetic approach to asymmetrically functionalized 1,3-di(2-pyridyl)benzenes starting from 3-(3-bromophenyl)-1,2,4-triazines using sequential aza-Diels-Alder reactions and Stille cross-coupling is reported. Photophysical properties of the obtained compounds are studied.

Keywords: 1,2,4-triazines; 1,3-di(2-pyridyl)benzenes; Aza-Diels–Alder reaction; Cross-coupling; Fluorescence.
