A fluorous tetraarylporphyrin has been prepared in a single reaction step starting from commercially available 5,10,15,20-tetrakis(4-hydroxyphenyl)porphyrin [TPP(OH)4]. The new compound was successfully employed as a sensitizer in photooxygenation reactions carried out under homogeneous conditions, showing activity comparable to the standard 5,10,15,20-tetraphenylporphyrin (TPP) sensitizer.

从市售的5,10,15,20-四(4-羟苯基)卟啉[TPP(OH)4]。新化合物已成功地用作在均相条件下进行的光氧化反应中的敏化剂,其活性可与标准的5,10,15,20-四苯基卟啉(TPP)敏化剂相媲美。还在氟双相条件下研究了光氧化反应,产生的产物分布有些不同。由于其氟性质,可以通过液-液或固相萃取轻松地从均匀混合物中除去新的卟啉。在氟双相反应的情况下,可以通过简单的相分离将氟敏化剂回收,然后再使用,至少在随后的五次运行中保持其效率。
