Fluorescent dyes with core structures of 2-(2-hydroxyphenol)benzoxazole (HBO) and 1,2,3-triazole (click triazole) were prepared through Heck cross-coupling and copper(I)-catalyzed azide-alkyne cycloaddition reactions, respectively. These dyes have interesting emission properties that can be altered through solvent selection or through the addition of an acid or base. Resulting from this, these emission-tunable fluorophores have potential applications in organic light-emitting diodes (OLEDs) and electronic displays. Dyes within these groups possess a large apparent Stokes shift (8,000 – 13,000 cm<sup>-1</sup>) and fair quantum yields (0.1 – 0.3). In addition, dyes derived from the HBO scaffold have shown some potential in excitation dependent emission, providing yet another avenue of emission color tuning.
