A series of novel 3-pyrryl fulgides and fulgimides are disclosed which are photochromic. The photochromic compounds are coloured by subjecting them to irradiation in the near ultraviolet and will revert to the colourless form on exposure to visible light, especially light having a wavelength in 600 to 650 nm band.
本研究公开了一系列具有光致变色功能的新型 3-
吡咯氟化物和
氟酰亚胺。将这些光致变色化合物置于近紫外光下照射会使其着色,而在可见光下,特别是波长在 600 至 650 纳米波段的光下,它们又会恢复到无色状态。
