  In-Line Monitoring and Spectral Analysis of Polymer Blend Dispersion in Microcompounder

  摘要：

  Microcompounders are the most common compounding machines for making polymer composites. The torque rheometry is an effective tool for predicting the processing characteristics of thermoplastic polymers. It provides continuous monitoring of torque and temperature data during compounding which is a measure of processability. In this work, we have studied the influence of processing parameters on the dispersion degree of an anthracene derivative (AMA) in a polystyrene matrix with respect to the rheological, structural, and optical properties. The chemical structure of the synthesized AMA as a tracer was confirmed by H-1 NMR and thermal properties were examined by DSC. In addition, a blend of polystyrene and AMA was spin-coated on a glass substrate to investigate oxidation stability confirmed by UV measurement. By using microcompounder, the polymer blend with the AMA tracer was mixed and it was visually indicated by fluorescent images.

  The Suzuki-Miyaura cross-coupling reaction is one of the most reliable methods for the construction of carbon-carbon bonds in solution. However, examples for the corresponding solid-state cross-coupling reactions remain scarce. Herein, we report the first broadly applicable mechanochemical protocol for a solid-state palladium-catalyzed organoboron cross-coupling reaction using an olefin additive. Compared

  铃木-宫浦交叉偶联反应是在溶液中构建碳-碳键的最可靠的方法之一。然而，相应的固态交叉偶联反应的例子仍然很少。在此，我们报告了第一个广泛适用的使用烯烃添加剂进行固态钯催化有机硼交叉偶联反应的机械化学方案。与之前的研究相比，新开发的方案显示出显着拓宽的底物范围。我们的机理数据表明，烯烃添加剂可能充当钯基催化剂的分散剂，以抑制纳米颗粒的更高聚集，也可以充当活性单体 Pd(0) 物质的稳定剂，从而促进这些具有挑战性的固态 CC 键形成交叉-偶联反应。

  9,10-Bis(3′,5′-diphenylphenyl)anthracene [MAM], 9-(3′,5′-diphenylphenyl)-10-(3‴,5‴-diphenylbiphenyl-4″-yl)anthracene [MAT], and 9,10-bis(3″,5″-diphenylbiphenyl-4′-yl)anthracene [TAT] were newly synthesized through boration and Suzuki aryl–aryl coupling reactions. We have demonstrated that the EL performance of blue-light emitters can be optimized and improved by varying the chemical structures of the side groups. In the thin film state, the three materials exhibit PLmax values in the range of 439–445 nm. MAM, MAT, and TAT all have high Tg values above 120 °C; TAT has the highest Tg value, above 150 °C. This is twice as high as that of DPVBi (64 °C) and is much higher than that of MADN (120 °C) as well. It also exhibits excellent color coordinates (0.156, 0.088), which are very close to the NTSC blue standard, and an external quantum efficiency of 7.18%, twice that of MADN, which are the best reported results for deep-blue OLED emitters.
