Excimer Fluorescence Quenching of Poly (styrene-co-acrylic acid)-Eu Complex by simple Hydrocarbons in Tetrahydrofuran Solutions
Doo Hee Park, Kang-Jin Kim*
Quenching of excimer fluorescence from polystyrene-acrylic acid copolymers containing Eu3+ has been studied in tetrahydrofuran solution using simple aromatic hydrocarbons as quenchers under steady-state conditions. Aromatic hydrocarbons quenched collisionally the excimer fluorescence and their rate constants of quenching were determined. The magnitude of quenching constant is interpreted in terms of the cube root of the molar volume of quencher. Cycloalkanes were not effective in quenching the excimer fluorescence possibly due to different solubility characteristics from aromatic hydrocarbons.
