我们观察了压力对离子液体中由2光化学生成的有色铬1热褪色速率的影响。随着[C-4-mim][CS]、[bzl-mint][Tf2N]和[mnp-mim][Tf2N]压力的增加，反应速率减慢，而随着[C-4-mim][Tf2N]压力的增加，反应速率增加。这些压力引起的延迟，即所谓的动态溶剂效应，是由溶剂的缓慢热波动引起的。
We observed pressure effects on the rate of thermal fading of colored chromene 1 photochemically generated from 2 in ionic liquids. The reaction rates were retarded with increasing pressure in [C-4-mim][CS], [bzl-mint][Tf2N], and [mnp-mim][Tf2N], whereas the reaction rate increased with pressures in [C-4-mim][Tf2N]. These pressure-induced retardations, so-called dynamic solvent effects, result from the slow thermal fluctuations of solvents.
