Abstract
A set of molecular salts with general formula [1H]nA·xH2O (1 = 4-amino-cinnamic acid, An- = NO3-, BF4-, PF6-, SO42-, x = 0, 1) was prepared and structurally characterized. [1H]Cl and [1H]2SO4·H2O(ii) were found to undergo an SCSC stepwise [2+2] photodimerization, which was followed by X-ray diffraction; a kinetic analysis was performed on single crystals of both salts. In the case of [1H]Cl the photoreaction was also studied on polycrystalline materials.File | Dimensione | Formato | |
