Polycyclic π-conjugated hydrocarbons (PCHs), either unfunctionalized or structurally
modified derivatives, have attracted tremendous interest in the past few decades as high …

Ladder‐like aromatic diketones (LADK), which possess a coplanar π‐extended geometry, a
high electron deficiency as well as various attractive optoelectronic properties, are …

Indeno [1, 2-b] fluorenes (IFs), while containing 4n π-electrons, are best described as two
aromatic benzene rings fused to a weakly paratropic s-indacene core. In this study, we find …

We demonstrate the preparation of diacenaphthopentalene derivatives via a palladium-
catalyzed dimerization of 1-iodo-2-arylethynyl-acenaphthylenes. The resulting 7, 14 …

New families of donor/acceptor semiconductors based on dihydroindeno [1, 2‐a] fluorene
and dihydroindeno [2, 1‐b] fluorene are reported. Due to the spiro bridges, this new …

Alkyl chains are basic units in the design of organic semiconductors for purposes of
enhancing solubility, tuning electronic energy levels, and tailoring molecular packing. This …

ABSTRACT A novel air-stable n-type benzothiaphene endcapped azaarene (BTPQ) and its
sulfonated derivative (BSPQ) were prepared via two pathways and characterized by NMR …

The design and synthesis of novel electron-deficient and solution-processable polycyclic
aromatic hydrocarbons offers great opportunities for the development of low-cost and large …

The synthesis and characterization of two benzo-indaceno-thiophene compounds (anti-BIT
and syn-BIT) are described. Two sequential Suzuki cross-couplings utilizing the halogen …

The synthesis and optical, electronic and structural properties of indenone-fused azaacenes
are reported. With different fused lengths and units composed of azaacenes, the electronic …
