Abstract

The synthesis of two new polyphenylene vinylene (PPV) precursor polymers which can be thermally induced to eliminate pentanol is presented. Pentanol has recently been discovered to be a very useful lubricant in MicroElectroMechanical Systems. The utilization of the elimination reaction of precursor polymers to PPV as a small molecule delivery platform has, to the best of our knowledge, not been previously reported. The elimination reactions were examined using thermal gravimetric analysis, gas chromatography, and UV-Vis spectroscopy. Using PPV precursors allows for (1) a high loading of lubricant (one molecule per monomeric unit), (2) a platform that requires relatively high temperatures (>145 °C) to eliminate the lubricant, and (3) a non-volatile, mechanically and chemically stable by-product of the elimination reaction (PPV).

摘要

介绍了两种新的聚对苯乙炔（PPV）前体聚合物的合成方法，这两种聚合物可以通过热诱导去除戊醇。最近发现戊醇在微机电系统（MicroElectroMechanical Systems）中是一种非常有用的润滑剂。据我们所知，利用前体聚合物到 PPV 的消除反应作为小分子输送平台尚未有报道。使用热重分析、气相色谱和紫外可见光谱法研究了消除反应。使用 PPV 前体可以实现：（1）高负载润滑剂（每个单体单元一个分子）；（2）需要相对较高温度（>145°C）来去除润滑剂的平台；以及（3）消除反应的非挥发性、机械和化学稳定的副产物（PPV）。
