摘要
在“拟高稀”条件下 ,以酚酞与甲基酚酞为双羟基型单体 ,与活性双氟基芳香化合物合成了聚芳醚酮环状齐聚物。通过基质辅助激光解吸电离飞行时间质谱对其环状结构进行了表征。
Cyclic ether ketone oligomers containing phenolphthalein moiety were prepared via the nucleophilic substitution reaction under pseudo high dilution conditions. The structures of cyclic aryl ether ketone were determined by using the technique of matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS).
