Multiple emissions from indenofluorenedione in solution and polymer films

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 w...

Description
Summary: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. An indenofluorenedione derivative with DAD framework exhibits the dual fluorescent channels, which can be controllably switched in broad visible range by changing environmental polarity, leading to sensitive multi-luminescence including white.
