The B2, N4-doped heptacene H4 in which two N, N′-dihydrophenazine units are linked by
two BMes bridges (Mes= mesityl) was synthesized via fourfold Buchwald− Hartwig coupling …

A highly modular synthesis of BNB-and BOB-doped phenalenyls is presented. Treatment of
the 1, 8-naphthalenediyl-bridged boronic acid anhydride 1 with LiAlH4/Me3SiCl afforded the …

Theoretical calculations predict a narrowing of band gap energies in the acene family with
each successive benzene ring addition up to hexacene, beyond which the HOMO–LUMO …

A series of alkyl (1− 3), aryl (6), and benzo-annulated (4, 5) heteroaromatic triphenylene
analogues with B2N2C2 cores have been synthesized via chelation of pyridazine …

The synthesis of bisalkynylated derivatives of tetrabenzo [a, c, p, r] heptacene and
tetrabenzo [a, c, l, n] pentacene via two‐/fourfold Stille reactions involving a 9 …

Sixfold TIPS‐ethynylation combined with fourfold bromination of the armchair edges
furnishes a long‐lived, soluble heptacene; π‐extension via Stille coupling accesses a …

The preparation of conjugated heteroheptacenes using an electrophilic coupling reaction
induced by a super acid is reported. The new molecules containing thiophene and/or pyrrole …

Two phenothiazine (PTZ) moieties were connected via naphthalene spacers to a central
arene to result in stacked PTZ‐arene‐PTZ structure elements. Benzene and …

Two new highly charged [2] catenanes—namely, m He [2] C· 6PF6 and m Ho [2] C· 6PF6—
were synthesized by exploiting radical host–guest templation between derivatives …

An approach for the synthesis of pyrene-fused acenes that allows the introduction of electron-
withdrawing cyano groups in key positions that simultaneously (i) induce twists in the …
