Tiny Molecule with Strong Fluorescence: BMeS-p-A

BMeS-p-A is a novel synthetic dye. Due to its unique and symmetrical molecular design, BMeS-p-A shows green fluorescence despite its small molecular size (Table 1). BMeS-p-A shows large Stokes shifts up to 140 nm due to a large conformation change in the excited-state.
The absorption and fluorescence properties of BMeS-p-A are independent of pH, solvents, or concentration (Figure 1,2). BMeS-p-A additionally shows high photo-stability. The unique and robust qualities of BMeS-p-A could be expected to be applied to a variety of applications.
