with substituted aryldiazenyl group led to the extension of conjugation that facilitated fluorescence emission in the visible region with a large stokes shift of 290–294 nm. The novelty of work is a synthesis of highly conjugated molecular assembly, high yield in shorter reaction time, energy efficiency, atom economy, utilization of water as a universal green solvent and meglumine as an eco-benign organo-catalyst
