説明
Fulgides are photochromic in solution and in the solid state. This study revealed that the photochromism of fulgide crystals proceeds in two stages. On the basis of a previously developed two-photon excitation method, a single-crystal X-ray diffraction study on (2E,3Z)-2-[1-(2,5-dimethyl-3-furyl)-2-methylpropylidene]-3-sec-butylidenesuccinic anhydride (3) allowed monitoring the structural changes in the solid state and confirmed that the photocyclization proceeded in a conrotatory fashion. The lattice-controlled photoreaction was, however, limited to the early photoconversion stages, where only a small amount of photogenerated colored species was present in the lattice of the reactant crystals. Upon further accumulation of the photoproduct, the reaction proceeded to a second stage, where the crystals of the photoproduct separated from the reactant-like crystals to form a different solid phase. The in situ observation of the solid-state photochromism was thus also limited to the early stages of the photoch...
