Facile synthesis of triphenylenes and triphenylene/phenanthrene fused heteroaromatics

Abstract

In the recent past, development of milder, safer and comparatively less toxic methods in organic synthesis has received great attention. We report a simple and facile method for the synthesis of substituted triphenylenes and their heteroaryl analogues using ceric ammonium nitrate (CAN) via oxidative biaryl coupling. We describe the structural and photophysical properties of these unique heteroaryl fused triphenylenes.
