Novel styrene-based oligoarylamine monomers are described which are suitable for the preparation of polymeric hole-transport materials, with very high glass transition temperatures. The monomers are prepared using the Wittig reaction from the appropriate aldehyde precursor, which was assembled using the classical Ullmann reaction. A number of the monomers yielded high-quality crystals which facilitated X-ray characterisation. Polymerisation was achieved either by solution free-radical initiation or by condensed phase thermal autopolymerisation. The latter suggests a method of initiator-free polymerisation which may have potential for multilayer device fabrication.
报道了一系列新型苯乙烯基低聚芳胺单体,这些单体适用于制备具有极高玻璃化转变温度的聚合物空穴传输材料。这些单体是通过Wittig反应从适当的醛前体合成得到的,而该醛前体则是通过经典的Ullmann反应组装而成的。其中多种单体生成了高质量的晶体,这有助于利用X射线进行表征。通过溶液自由基引发或通过缩聚相热自聚合可以实现聚合。后者提示了一种无需引发剂的聚合方法,该方法可能在多层器件制造中具有潜在应用价值。
