合成了一种具有两个弱给电子取代基的吲哚芴二酮衍生物（IFO），该衍生物具有包括白色在内的多色发光。通过在较宽的可见范围内改变溶剂和聚合物基质，可以控制多个荧光通道的切换。研究还表明，嵌入聚苯乙烯基体中的IFO对环境极性敏感，因此在暴露于极性有机溶剂时表现出发射颜色的变化。
A new indenofluorenedione derivative (IFO) with two weak electron-donating substituents was synthesized, and exhibited a multi-coloured emission including white. The multiple fluorescent channels can be controllably switched by changing the solvent and polymer matrix in a broad visible range. It was also demonstrated that IFO embedded in a polystyrene matrix is sensitive to environmental polarity, thus exhibiting the emission colour changes upon exposure to polar organic solvents.
