polymer supports that could be used in thermomorphic and latent biphasic systems useful in synthesis and catalysis were evaluated using polymers tagged with either visible dyes or fluorescent probes. Heptane/DMF, heptane/90% ethanol−water, heptane/ethyl acetate, heptane/ethanol, and heptane/tert-butyl alcohol solvent mixtures were all studied as examples of thermomorphic or latent biphasic systems
使用标记有可见染料或荧光探针的聚合物评估了可用于合成和催化的热态和潜在双相系统中的聚合物载体的相选择性溶解度特性。庚烷/DMF、庚烷/90% 乙醇-水、庚烷/乙酸乙酯、庚烷/乙醇和庚烷/叔丁醇溶剂混合物都作为热晶型或潜在双相系统的例子进行了研究。测试了一系列聚合物,包括聚异丁烯 (PIB)、聚(叔丁基苯乙烯) (PTBS)、聚(丙烯酸十八烷基酯) (PODA) 和聚(甲基丙烯酸十八烷基酯) (PODMA) 的疏水相选择性溶解度。这些研究的结果与之前使用极性和非极性聚(N-烷基丙烯酰胺)和聚苯乙烯的工作进行了比较。连同之前的这项工作,
