合成了一系列无环对甲基和对叔丁基苯酚甲醛四聚体的部分或全部亚甲基桥被硫桥取代的化合物。结果表明，虽然硫桥连四聚体与多种有机化合物形成了结晶状的主-客体复合物，但它们的包结行为与母体四聚体不同。硫桥的数目和位置以及苯酚的对位取代基对包结性能有很大的影响。由热解离速率估算的硫桥四聚体（SSS-a，B）与苯的复合物的热稳定性低于母体四聚体（CCC-a，B）。
A series of compounds in which a part or all of the methylene bridges of acyclic p-methyl- and p-t-butylphenol-formaldehyde tetramers were replaced by sulfur bridge(s) was synthesized. It was found that though the sulfur-bridged tetramers formed crystalline host-guest complexes with a variety of organic compounds, they were different from the parent tetramers regarding their inclusion behavior. The number and position of the sulfur bridge(s), as well as the p-substituent of phenol in the tetramers, had a great influence upon the inclusion property. The thermal stability of complexes of the sulfur-bridged tetramers (SSS-a,b) with benzene, as estimated from their thermal dissociation rates, are lower than those of the parent tetramers (CCC-a,b).
