Synthesis and sensing properties of triphenylamine based dye sensor

We have designed and synthesized a triphenylamine-based new dye sensor and corresponding selective and sensitive detection functions for heavy metal ions were investigated. The complex potentials for heavy metal ions were characterized by the measurements of optical properties using UV-Vis spectrophotometer and spectrofluorophotometer. Furthermore, the molecular energy levels of the designed dye sensors were also computationally optimized and calculated by the density function theory (DFT) with exchange correction functional of local density approximation (LDA) based on the Perdew-Wang (PWC) set and cyclic voltammetry.
