High performance solution processable n-type organic semiconductor is an essential element to realize lowcost, all organic and flexible composite logic circuits. In the design of n-type semiconducting materials, tuning the LUMO level of compounds is a key point. As a strong electron withdrawing unit, the introduction of chlorine atom into the chemical structure can increase the electron affinity of the material and reduce the LUMO energy level. Here, a series chlorine substituted N-heteroacene analogues of 6,7,8,9tetrachloro-4,11-bis(4-((2-ethylhexyl) ,2,3,4,8,9,10,11-octachloro-6,13-bis(4-((2ethylhexyl)oxy)phenyl)quinoxalino[2,3-b]phenazine (8Cl) and 12Cl have been synthesized and characterized. Solutionprocessed organic field-effect transistors (OFETs) based on these four compounds exhibit good electron mobilities of 0.04 cm 2 V À 1 s À 1 , 0.01 cm 2 V À 1 s À 1 , 2 × 10 À 3 cm 2 V À 1 s À 1 and 3 × 10 À 3 cm 2 V À 1 s À 1 , respectively, under ambient conditions. The results suggest that these chlorine substituted π-conjugated N-heteroacene analogues are promising n-type semiconductors in OFET applications.

“…The PTBF7 copolymer was synthesized by introducing alkylthio phenyl as the substituted group into the TBF unit. [ 274 ] Benefited from the good absorption and deep HOMO level, the PTBF7 :PC 71 BM devices rendered an efficient PCE of 6.55%. To research the effect of side chains on the photovoltaic performance of TBF‐based polymers, they synthesized two medium bandgap copolymers PTBF8 and PTBF9 in which using different side chains substituted TBF as donor units and BDD as acceptor unit.…”

The state‐of‐the‐art bulk‐heterojunction (BHJ)‐type organic solar cells (OSCs) have exhibited power conversion efficiencies (PCEs) of exceeding 18%. Thereinto, thiophene and its fused‐ring derivatives play significant roles in facilitating the development of OSCs due to their excellent semiconducting natures. Furan as thiophene analogue, is a ubiquitous motif in naturally occurring organic compounds. Driven by the advantages of furan, such as less steric hindrance, good solubility, excellent stacking, strong rigidity and fluorescence, biomass derived fractions, more and more research groups focus on the furan‐based materials for using in OSCs in the past decade. To systematically understand the developments of furan‐based photovoltaic materials, the relationships between the molecular structures, optoelectronic properties, and photovoltaic performances for the furan‐based semiconductor materials including single furan, benzofuran, benzodifuran (BDF) (containing thienobenzofuran (TBF)), naphthodifurans (NDF), and polycyclic furan are summarized. Finally, the empirical regularities and perspectives of the development of this kind of new organic semiconductor materials are extracted.
