Acyclic para-substituted phenol–formaldehyde oligomers (R=H, Me, n-Bu, t-Bu, and cyclohexyl; the number of phenol units=3–6) form host–guest complexes with various organic compounds. The inclusion property of the acyclic oligomers is greatly influenced by the p-substituents of phenol and the number of phenol units in the oligomers; for example, a) while the t-butyl tetramer is effective, the corresponding butyl tetramer has a poor ability for the complex formation, and b) the tetramers and pentamers are good hosts for organic compounds, forming 2:1 (host:guest) complexes in many cases.
非环状对取代的酚-甲醛低聚物(R=H, Me, n-Bu, t-Bu 和环己基;酚单位数量=3-6)与各种有机化合物形成宿主- guest 复合物。非环状低聚物的包容特性受到酚的对位取代基和低聚物中酚单位数量的显著影响;例如,a) 尽管叔丁基四聚物表现有效,但对应的正丁基四聚物在复合物形成方面能力较差,b) 四聚物和五聚物对有机化合物是良好的宿主,在许多情况下形成2:1(宿主: guest)复合物。
