  Synthesis and characterization of fluorinated benzoxazole polymers with highTg and low dielectric constant

  摘要：

  Next generation microelectronic packaging requirements are driving the need to produce increasingly lower dielectric constant materials while maintaining high thermal stability and ease of processing. Efforts have focused on the synthesis and analysis of new polymers with the goals of high thermal stability [degradation temperature (T-d) > 400 degrees C, low glass-transition temperature (T-g) > 350 degrees C], low water uptake (<1%), solubility in selected organic solvents, dielectric constant less than 2.5, and low thermal expansion coefficient. These stringent combined goals have been largely achieved with flexible aromatic benzoxazole polymers. Intramolecular hydrogen bonding between pendant hydroxyl groups and the double-bond nitrogen of the benzoxazole has been exploited to increase the polymer T-g, whereas the incorporation of perfluoroisopropyl units effectively decreases the dielectric constant. Out-of-plane impedance measurements on films of materials in this family (38-134 mu m thick) have resulted in typical dielectric values of 2.1-2.5 at 1 MHz, depending on copolymer ratios and functionalizations. Results have been correlated with optical waveguide measurements of films 4-mu m thick to determine film anisotropy and the high-frequency dielectric constant, and have been corroborated by in-plane interdigitated electrode dielectric measurements on samples 0.75 mu m thick. Candidate materials exhibited extremely low water uptake (0.2%) even after submersion in boiling water for several days. Dynamic mechanical analysis of the polymers enabled the determination of the influence of intermolecular hydrogen bonding on the T-g and loss tangent magnitude. Finally, the coefficient; of thermal expansion has been examined and correlated with copolymer constitution. (C) 2000 John Wiley & Sons, Inc.

  efficiently constructed with sole 1-DNQs as arylation reagents under one set of reaction conditions. The judicious selection of palladium catalytic system plays a pivotal role in the excellent selectivities. This transformation accommodated fairly broad substrate generality for both 2-naphthol and N-Boc-2-naphthylamine and afforded the structurally diversified BINOLs and NOBIN derivatives in high efficiency

  在一组反应条件下，使用唯一的 1-DNQ 作为芳基化试剂有效地构建了特权联芳基框架 BINOL 和 NOBIN。钯催化体系的明智选择对优异的选择性起着关键作用。这种转变为 2-萘酚和N提供了相当广泛的底物通用性-Boc-2-萘胺并高效地提供了结构多样化的BINOLs和NOBIN衍生物。值得注意的是，在常规钯催化反应中无法存活的溴取代基与这组条件非常兼容，为进一步丰富 BINOL 和 NOBIN 库提供了有效的手段。对该反应的不对称变体也进行了初步尝试，用于 BINOLs 合成的比例高达 80:20。
• Optimized Speech Understanding with the Continuous Interleaved Sampling Speech Coding Strategy in Patients with Cochlear Implants: Effect of Variations in Stimulation Rate and Number of Channels

  The purpose of this study was to investigate the effect of systematic variations in stimulation rate and number of channels on speech understanding in 13 patients with cochlear implants who used the continuous interleaved sampling speech coding strategy. Reducing the stimulation rate from 1,515 to 1,730 pulses per second per channel to 600 pulses per second per channel resulted in decreased overall performance; the understanding of monosyllables and consonants was more affected than the understanding of vowels. Reducing the number of active channels below 7 or 8 channels decreased speech understanding; the identification of vowels and monosyllables was most affected. We conclude that vowel recognition with the continuous interleaved sampling strategy relies on spectral cues more than on temporal cues, increasing with the number of active channels, whereas consonant recognition is more dependent on temporal cues and stimulation rate.

  这项研究的目的是调查刺激速率和通道数量的系统变化对使用连续交错采样语音编码策略的13名植入人工耳蜗患者的语音理解的影响。将刺激速率从每通道每秒1,515脉冲降低到每通道每秒600脉冲导致整体表现下降；单音节和辅音的理解受影响程度较大，而元音的理解受影响较小。将活跃通道数量降至7或8个以下会降低语音理解；元音和单音节的识别受影响最大。我们得出结论：使用连续交错采样策略的元音识别更多依赖于频谱线索而不是时间线索，随着活跃通道数量的增加而增加，而辅音识别更依赖于时间线索和刺激速率。
