characterization of several new polymers that are considered one-dimensional prototypes for the polaronicferromagnetic are reported. Synthesis involved either Wittig or Suzuki coupling to produce polymers with extended pi} systems. Oxidative doping (Isub 2} or AsFsub 5}) produces radical cations (polarons) that are stable at room temperature. Magnetic characterization of the dopedpolymers, using SQUID-based

A series of low-band-gap π-conjugated molecules comprising N,N′-dihexylindolo[3,2-b]indole as an electron donor (D) and dicyanovinyl as an electron acceptor (A) with A–π–D–π–A architecture have been designed and synthesized to fabricate a single-component ambipolar organic field-effect transistor (OFET). Molecules with different π-bridging units (none, thiophene, and bithiophene) were synthesized and
一系列低带隙π共轭分子,其中N,N′-二己基吲哚[3,2- b ]吲哚为电子供体(D),双氰基乙烯基为电子受体(A),A–π–D– π–A体系结构已被设计和合成,以制造单组分双极性有机场效应晶体管(OFET)。合成了具有不同π桥联单元(无,噻吩和联噻吩)的分子,并对其进行了表征,以研究其结构与性质的相关性。通过分子内电荷转移(ICT)相互作用和共轭作用扩展的协同作用,在溶液状态下,新合成的分子的带隙减小到1.41 eV。除其他化合物外,2H2TIDID-DCV(具有噻吩π-间隔物)表现出高度平衡的双极性电荷传输,其与来自真空沉积的OFET装置的空穴和电子迁移率分别为0.08cm 2 V -1 s -1和0.09cm 2 V -1 s -1。使用旋涂OFET器件OD2TIDID-DCV,其中的己基侧链2H2TIDID-DCV是由2-辛基十二烷基基团取代,也表现出双极性电荷输送性质(9.67×10迁移率-2厘米2
Double anchor indolo[3,2-<i>b</i>]indole-derived metal-free dyes with extra electron donors as efficient sensitizers for dye-sensitized solar cells
designed, synthesized, and applied for dye-sensitizedsolarcells (DSSCs). In this study, the effect of the additional donors was investigated by the replacement of the typical N-alkyl side chain using methoxyphenyl (dye 1) and hexyloxyphenyl (dye 2) as secondary donor groups. Molecular dyes-based di-anchoring models enhanced the significant interaction between sensitizing dyes and the TiO2 surface as well
设计,合成了两种基于吲哚[3,2- b ]吲哚供体主链和额外电子供体的新型无二受体金属的有机染料,并将其用于染料敏化太阳能电池(DSSC)。在这项研究中,通过使用甲氧基苯基(染料1)和己氧基苯基(染料2)作为次级供体基团替换典型的N-烷基侧链,研究了其他供体的作用。基于分子染料的双锚定模型增强了增感染料与TiO 2之间的显着相互作用与熟悉的核心吲哚-吲哚供体相比,该表面具有更好的集光效率。在全球标准条件1.5 AM下,基于染料2的电池的整体转换效率提高了7.86%,而基于标准N719的商业电池的整体转换效率为8.08%。因此,具有额外供体的双锚吲哚[3,2- b ]吲哚是有效DSSC的有希望的候选者。
