  Modular Access to 9,9-Spirobifluorenes by Oxidative Coupling Using Molybdenum Pentachloride

  摘要：

  The strong oxidizing agent molybdenum pentachloride was used for an efficient direct C-C bond formation of 9,9-diarylfluorenes to the corresponding 9,9-spirobifluorenes. Thus, a versatile method that is compatible with labile groups, such as iodo moieties, was established. By this approach important building blocks for light emitting polymers were synthesized in high yields.

  as a signaling platform via 1‐step and 2‐step fluorescence resonance energy transfer. Guanine‐rich K+‐specific aptamers were designed as K+ ion recognition species with 6‐carboxyfluorescein (6‐FAM) and 6‐carboxytetramethylrhodamine (6‐TAMRA) at both termini. In the presence of K+ ions, the aptamers undergo a conformational change from an unfolded to folded form by forming a G‐quadruplex with K+, bringing

  通过染料标记的适体和共轭聚电解质（CPE）作为信号传递平台，通过1步和2步荧光共振能量转移，开发了一种新的钾离子检测测定法。富含鸟嘌呤的K +特异性适体被设计为在两个末端均带有6-羧基荧光素（6-FAM）和6-羧基四甲基罗丹明（6-TAMRA）的K +离子识别物种。在存在K +离子的情况下，适体通过与K +形成G-四链体而发生构象变化，从未折叠形式变为折叠形式，从而使两种染料接近。FRET引起的6-TAMRA发射成正比[K + ]的范围为22.5μ米-100米米在水中不受过量Na +离子（100 m m）的干扰。添加CPE时，启用了从CPE通过6-FAM到6-TAMRA的两步FRET过程，显示了带有K +离子的增强的6-TAMRA信号。动态检测范围和检测限（LOD）的限为微调从~millimolar至K的~nanomolar浓度+通过调制CPE的信号放大效果。LOD被确定为≈3.0n m。

  A highly soluble polyfluorene-based copolymer containing electron-rich triphenylamine (TPA) and electron-poor 9,9-bis(3,4-bis(3,4-dicyanophenoxy)phenyl side chains in the C-9 position of the fluorene unit was synthesized under Yamamoto conditions. By applying 306 nm as excitation wavelength, the resultant polymer exhibits strong photoluminescence with maximum emission peaks centered at 413 and 433(sh) nm in chloroform. The calculated highest occupied molecular orbital (HOMO), lowest unoccupied molecular orbital (LUMO), energy bandgap, ionization potential, and electron affinity are -5.66, -3.44, 2.22, 5.92, and 3.70 eV, respectively. The as-fabricated polymer film exhibited typical stable write-once-read-many-times (WORM) memory characteristics, which are desirable for ultralow-cost permanent storage of digital images. The currents in both ON and OFF states did not show any degradation, suggesting good device stability. The ON/OFF current ratio observed in the sweep I-Vcharacteristics at +1.0 V is 6.1 x 10(3). The conduction mechanism through ITO/polymer/Al device is discussed.
