Synthesis of a Fluorophore with Improved Optical Brightness.

The synthesis and characterization of a novel fluorophore(), with potential application as an optical brightener are reported. This compound was prepared by reacting 4,4-diaminostilbene-2,2-disulfonic acid with cyanuric chloride in the presence of NaCO followed by the addition of trityl aniline. Solution and solid state fluorescence demonstrated a strong blue/purple emission centered at 450 nm.
