| The photochemical of arylazides in fluid media, such as in a gas phase or in solution, is controlled by concentrations of substrates and reaction temperatures since the reactant molecules can diffuse freele. On the other hand, diffusional behavior of reactant molecules in crystals are severely suppressed due to the tight packing in the three dimensionally ordered arrangement. Chemical reactivity in the solid phase depends on the distance and relative orientation of the reaction sites of the reacting molecules. Sometimes higher regio- and stereoselectivity in the product formation is observed in crystals. The contrasting photochemistry of arylazides in solution and in crystals will be discussed. |
