We show that ultrasound-induced mechanical force isomerizes an azobenzene centered within a poly(methyl acrylate) polymer from cis to trans configuration without cleaving the azo bond. The isomerization rate was not altered by the polarity of the solvent indicating that the isomerization occurs through a non-polar, inversion transition state.
我们展示了超声波诱导的机械力能在不切断偶氮键的情况下将位于聚甲基丙烯酸酯聚合物中心的偶氮苯异构体从顺式转变为反式构型。异构化速率不受溶剂极性的影响,表明异构化过程是通过非极性的反转过渡态发生的。
