文摘

We have synthesized a series of novel coplanar chromophores in which heteroarenes, namely, thiophene, benzothiophene, and carbazole,were fused to neighboring phenylene ring(s) through intramolecular annulation via sp³-hybridized carbon atoms bearing two p-tolyl groups asperipheral substituents. The molecular configurations of the -conjugated backbones were determined by X-ray crystallographic analysis; theheteroarene-fused molecular frameworks of these novel molecules exhibit nearly coplanar conformations.
