A novel donor-acceptor type aminobenzodifuranone based chromophore molecule, coded as ABDF, with a benzodifuranone (BDF) core as acceptor and an N-ethylamino side chain as donor moiety was synthesized and used in single crystal organic field-effect transistors (OFETs). The optical, thermal, electrochemical properties of ABDF were also investigated. Compared to other BDF or halogenated BDF analogs, the solution absorption of ABDF exhibits large bathochromic shift over 100 nm, indicating the strong intramolecular charge transfer intensity within the molecules. In particular, the incorporation of amino groups into the BDF core also enables the formation of intermolecular hydrogen-bonding interactions in the solid states of ABDF as proved by the FT-IR results. The crystalline ABDF based OFET devices was simply prepared by drop-casting the ABDF solution on to the electrode-prepatterned substrates, giving a hole mobility as high as 0.42 cm²/V·s without large degradation after store in ambient environment for up to two months. ABDF is a promising chromophore for high performance organic field-effect transistors.

一种新型的供体-受体型氨基苯并二呋喃酮基发色团分子，编码为ABDF，以苯并二呋喃酮（BDF）核为受体，N合成了作为供体部分的-乙基氨基侧链，并将其用于单晶有机场效应晶体管（OFET）。还研究了ABDF的光学，热，电化学性质。与其他BDF或卤代BDF类似物相比，ABDF的溶液吸收在100 nm处表现出大的红移，表明分子内分子内的电荷转移强度很强。特别地，如FT-IR结果所证实的，将氨基结合到BDF核心中还使得能够在ABDF的固态中形成分子间氢键相互作用。通过将ABDF溶液滴铸到电极预图案化的衬底上，可以简单地制备基于晶体ABDF的OFET器件，从而获得高达0.42 cm ²的空穴迁移率/ V·s在周围环境中存放长达两个月后，不会出现较大的降解。ABDF是用于高性能有机场效应晶体管的有前途的生色团。
