Synthesis and photophysical properties of amino-substituted benzodithiophene-based fluorophores†
An amino-substituted benzodithiophene was synthesized by a TiCl4 promoted reaction. It was used to construct a series of acetylene-containing fluorophores, which exhibit intense fluorescence in solutions and solid states with large Stokes shifts. The emission colour can be modulated from green to red by changing the terminal groups. These fluorophores may have potential applications in optoelectronic devices and fluorescent sensors.
