46_23/2007Cover Picture: 3-Boryl-2,2'-bithiophene as a Versatile Core Skeleton for Full-Color Highly Emissive Organic Solids (Angew. Chem. Int. Ed. 23/2007)

Full-color highly emissive organic solids with fluorescence maxima ranging over a wide visible region (blue to deep red) can be produced by using 3-boryl-2,2-bithiophene as a core skeleton. In their Communication on page 4273 ff., S. Yamaguchi and co-workers describe the molecular design of emissive organic materials in which intramolecular charge transfer from the π-conjugated moiety to the boron moiety in the twisted framework plays a crucial role for attaining intense solid-state emissions with large Stokes shifts.
