    通过炔烃取代来调节4,8-二取代的苯并二恶唑的光学和电子性质
    摘要:
    为了设计用于合成共轭材料的新的电子不足的结构单元,一系列新的反式合成了在4,8-位带有卤素或炔基取代基的苯并二恶唑。此外,还研究了这些修饰对光学和电子性能的影响。理论计算预测,各种炔烃的掺入可用于调节这些小分子的能级和带隙。使用两步反应序列,可以容易地以高收率制备目标4,8-二取代的苯并二恶唑:路易斯酸催化原酸酯环化,然后进行Sonogashira交叉偶联。实验确定的这些4,8-二取代的苯并二恶唑的HOMO值在-4.97至-6.20 eV的范围内,并且与理论预测值显示出合理的相关性,百分比偏差在2.4-12.8%的范围内。然而,当理论值外推至长链极限并与含有4,8-二取代的苯并双恶唑的共聚物进行比较时,实际HOMO值与预测HOMO值之间的偏差降低至小于3.5%。总的来说,这些结果表明这些4,8-二取代反式苯并二恶唑可用于合成具有可变和可预测电子特性的新型共轭材料。

    摘要 本文介绍了末端带有正烷氧基链或 3,7-二甲基辛氧基支化基团的新型吡啶基甲酯的合成、结构和介晶表征。通过偏光显微镜和差示扫描量热法研究了新型吡啶基棒状分子的液晶性质。新化合物在可变的介晶范围内表现出对映性近晶 A 中间相,具体取决于烷氧基链长度和末端支化。手性或外消旋形式的支链末端基团的存在通过保持中间相类型导致介晶范围的急剧增加以及结晶点的降低。

  • Nucleophilic Substitution in 16π-Antiaromatic System: Synthesis of Heteroatom-substituted Dibenzopentalenes

    An antiaromatic compound, 5-bromo-10-iododibenzopentalene, underwent nucleophilic substitution of heteroatoms such as R2NLi, ROLi, and RSLi. This substitution proceeded preferentially at the bromopentalene moiety than at the iodo-counterpart. Combining this substitution and Sonogashira coupling enabled syntheses of π-systems expanded by a dibenzopentalene array and heteroatom(s).

These dihalo-substituted pentalenes reacted with terminal ethynes in Sonogashira coupling and with arylboronic acid in Suzuki–Miyaura coupling to give a series of phenylethynyl- and/or aryl-substituted pentalenes. Suzuki–Miyaura coupling of the halopentalenes with in situ prepared pentaleneboronic esters provided bis-, tri-, and tetra(dibenzopentalene)s. It was found that

  • Synthesis of new iridium complexes and their electrophosphorescent properties in polymer light-emitting diodes
    作者:Weiguo Zhu、Chuanzhen Liu、Lijun Su、Wei Yang、Ming Yuan、Yong Cao

    日期:2003.12.10
    Several new iridium complexes with p-substituted 2-phenylpyridine (R-PPy) ligands have been synthesized and characterized. The complexes were incorporated into phosphorescent polymer light-emitting devices using soluble poly[1,4-bis(6′-cyano-6′-methylheptyloxy)phenylene] (CNPPP) as the host and the resultant materials compared with Ir(PPy)3-doped devices. Green electrophosphorescence was observed, with peak emission at about 495 and 515 nm. Among the devices fabricated, highly efficient polymer light-emitting diodes were obtained with CNPPP doped with fac-tris[2-(4-tert-butylphenyl)pyridinato]iridium. An external quantum efficiency of 4.4% (photoluminescence/electroluminescence) and a luminous efficiency of 10 cd A−1 were obtained at 120 cd m−2. These values remain at 4.2% and 10 cd A−1, respectively, at 2500 cd m−2. The improvement is attributed to improved interaction between the guest and host, and to better and more complete energy transfer from the host singlet to the guest triplet state. These results demonstrate that efficient electrophosphorescence is not limited to small molecule organic light-emitting diodes, it can also be achieved in devices made with polymer hosts.
