title: Saddle shaped hexaaryl[a,c,fg,j,l,op]tetracenes from 4,5,9,10-tetrafunctionalized pyrenes.
abstract: A new K-region functionalized pyrene is presented which was used as a building block for the straightforward synthesis of hexaaryl[a,c,fg,j,l,op]tetracene via fourfold Stille coupling and subsequent cyclodehydrogenation. Electronic properties and crystal structures are provided and reveal a saddle conformation for the curved hexaarylated tetracenes.
