More recently, N\u2010heteroacenes have been prepared. These molecules have been shown to be more stable and can exhibit n\u2010channel semiconductor properties.

These new \u03c0\u2010conjugated scaffolds show broad and intense absorption in the visible region and possess low\u2010lying HOMO and LUMO levels, leading to much better stability compared to that of
