Saddle Shaped Hexaaryl[a,c,fg,j,l,op]tetracenes from 4,5,9,10-Tetrafunctionalized Pyrenes

[摘要]：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.(1)
