The chemistry of radicals adsorbed on zeolites is remarkable in that the products of radical-radical reactions, which are nonselective in solution, can be made selective and can be controlled by supramolecular effects and magnetic isotope effects. The photolysis of ketones adsorbed on zeolites can be manipulated so that either primary or secondary radicals produced by photolysis can be directed to selected radical-radical reactions which are unknown in solution.
吸附在沸石上的自由基的化学性质非常显著,因为在溶液中无选择性的自由基-自由基反应产物,可以通过超分子效应和磁同位素效应变得具有选择性并得到控制。吸附在沸石上的酮的光解可以被操控,使得光解产生的一级或二级自由基能够导向溶液中未知的特定自由基-自由基反应。
