Optimising the synthesis and red-green-blue emission of a simple organic dye

Synthetic dyes have been widely used in supramolecular chemistry not only to probe fundamental chemical interactions but also as components of functional materials. Most current efforts in this regard are directed at designing new host systems for the dyes. Herein we report on the study of a versatile new organic fluorophore. We describe a synthesis which affords improved yields in a convenient one pot procedure. Moreover, a simple method for predicting and controlling the dye's responses to external stimuli affords a potentially practical method for achieving red-green-blue and concomitant white light generation.
