- 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.
