quinoxaline-fused tetrathiafulvalene (TTF) derivative 1 has been synthesized to form a compact and planar π-conjugated donor–acceptor (D–π–A) ensemble, and its single crystal structure has been determined by X-ray diffraction. The inherent redox activity of 1 has been probed by cyclic voltammetry, and UV-vis spectroscopy revealed the typical broad and intense intramolecularcharge-transfer (ICT) absorption
已合成喹喔啉融合的四硫富瓦烯(TTF)衍生物1,以形成紧凑且平面的π共轭供体-受体(D-π-A)集成体,并已通过X射线衍射确定了其单晶结构。的固有氧化还原活性的1已经通过循环伏安法进行探测,和UV-vis光谱揭示了典型的广泛和强烈的分子内电荷转移(ICT)吸收存在的这种紧凑地稠合的d-π-A分子。与碘反应生成2 :1的半导体电荷转移盐(1)2 I 3},但其单晶结构研究强调了在有机晶格中明显的电荷局部化的发生。因此,的(导电率1)2我3 },由四个接触方法上的单晶测量,只给了约1×10一个有限值-4 Ω -1厘米-1,求出活化能大约为470–480 meV。
