macrocyclic thioethersulfones with hydrogen peroxide affords a series of sulfone-linked paracyclophanes, [-Ar-SO2-]4, [-Ar-SO2-]6, [-Ar-SO2-]8 and [-Ar-SO2-]12. Single crystal X-ray analysis reveals [Ar-SO2-]4 to be a near-perfect square box, whilst the cyclic hexamer [-Ar-SO2-]6 adopts a much more irregular conformation. and [-Ar-SO2-]8 displays a "double-box" structure clearly related to that of [Ar-SO2-]4

Corona[5]arenes, a novel type of macrocyclic compound that is composed of alternating heteroatoms and para‐arylenes, were synthesized efficiently by two distinct methods. In a macrocycle‐to‐macrocycle transformation approach, S6‐corona[3]arene[3]tetrazine underwent sequential SNAr reactions with HS‐C6H4‐X‐C6H4‐SH (X=S, CH2, CMe2, SO2, and O) to produce the corresponding corona[3]arene[2]tetrazines
电晕[5]芳烃是一种由交替的杂原子和对亚芳基交替组成的新型大环化合物,可通过两种不同的方法有效地合成。在从大环到大环的转化方法中,S 6-电晕[3]芳烃[3]四嗪与HS-C 6 H 4 -X-C 6 H 4 -SH进行顺序的S N Ar反应(X = S,CH 2,CMe 2,SO 2和O)生成相应的电晕[3]芳烃[2]四嗪。还可以通过HS-C 6 H 4的单锅三组分反应以直接的方式构建不同的电晕[3]芳烃[2]四嗪化合物‐X‐C 6 H 4 ‐SH(X = S,CH 2,CMe 2,SO 2和O)与2,5-二巯基对苯二甲酸二乙酯和2当量的3,6-二氯四嗪在非常温和的条件下。所有电晕[5]芳烃在晶体状态下均采用1,2,4-交替构象结构,产生相似的近乎规则的五边形腔。所获得的大环的腔尺寸和电子性质都通过桥接元素X的性质进行了微调。

Two kinds of high glass temperature poly(arylene ethersulfone)s containing thioether and biphenyl units (PASSs) have been developed. The polymers were prepared by a polycondensation reaction of 4,4′-bis(4-chlorophenylsulfone)biphenyl (BCPSB) and 4,4′-dimercaptodiphenyl sulfone (DMDPS) (or 4,4′-bis(4-mercaptophenylsulfone)biphenyl (BMPSB)). They showed good thermal properties such as a relatively high
已经开发出两种含有硫醚和联苯单元(PASS)的高玻璃温度的聚(亚芳基醚砜)。通过4,4'-双(4-氯苯基砜)联苯(BCPSB)和4,4'-二巯基二苯砜(DMDPS)(或4,4'-双(4-巯基苯砜)联苯( BMPSB))。它们表现出良好的热性能,例如较高的玻璃化转变温度263–282°C和5%的失重温度(T 5%)441–445°C。所得膜的水通量和保留率是0.61–2.48 L m -2 h -1和89.47–94.91%分别。有趣的是,我们发现通过氧化处理,膜的耐腐蚀性已大大提高。它们甚至不溶于NMP,DMSO,浓H 2 SO 4,王水等,而没有氧化的聚合物在上述溶剂中可溶或被破坏。另外,我们发现氧化膜的水通量也得到改善,但保留率仅降低了一点。
