✦ Synopsis

We have designed and synthesized a 2,2-bithiophene-based new dye chemical sensor, and its selective and sensitive recognizing functions toward heavy metal cations were investigated. These find results were characterized using UV-Vis. spectrophotometer and spectrofluorometer. In addition, electrochemical properties were measured with cyclicvoltammetry test. Electron density distributions and HOMO/LUMO energy levels were computationally calculated and optimized. The energy levels of HOMO/LUMO were compared with computational calculation and cyclicvoltammetry measurement for each value. Finally, the formation type of metal ion bindings was determined by Job's plot measurements.
