摘　　要：应用激光解吸电离飞行时间质谱法对芳香环状聚硫醚醚砜低聚物结构进行了分析,比较了四种不同基质对环状物结构分析结果的影响,发现1,8,9 蒽三酚为此类芳香环状低聚物的有效基质。探讨了金属阳离子对此类芳香环状低聚物的影响,认为三氟乙酸银是此种芳香环状低聚物的有效阳离子剂。The structure of cyclic aryl thioether ether sulfone oligomers was characterized by MALDI-TOF-MS. Four kinds of matrix were compared and the results showed that 1,8,9-dithranol was the effective matrix. The effect of metal cationization agents on this kind of novel aromatic cyclic oligomers was studied and silver trifluoracetate was considered as a suitable cationization agent.
