ene]-4-(1-methylethylidene)tetrahydro-2,5-furandiones, were synthesized. These compounds were obtained as E-isomers, as demonstrated by X-ray diffraction, electronic spectroscopy, and 1H NMR spectroscopy. Fulgides exhibit photochromic properties in solution. The cyclic dihydrocarbazole photoisomers of indolylfulgides show fluorescence properties and are characterized by high thermal stability.
新的 3-indoylfulgides,即 3-[1-(1-aryl-5-methoxy-2-methyl-1H-indol-3-yl)ethylidene]-4-(1-methylethylidene)tetrahydro-2,5-合成呋喃二酮。X 射线衍射、电子光谱和 1 H NMR 光谱证明,这些化合物是作为 E 异构体获得的。Fulgides 在溶液中表现出光致变色特性。吲哚基硫化物的环状二氢咔唑光异构体显示出荧光特性,并具有高热稳定性的特点。
