Synthesis, Crystal Structures And Photoelectricity Of Triphenylamine Cyanoacetic Acid Complexes

The diverse applications of triphenylamine-based dyes in nonlinear optical materials, organic dye-sensitized solar cells, organic light-emitting diodes and electrochromism were due to their electron donor ability, good solubility, low redox protential, excellent hole-transporting property and easy film-formation. However, in order to overcome the disadvantages that pure organic dyes always show low optical and thermal stability, many researches have been made via hybrid of organic and inorganic materials. This hybrid materials exhibit the excellent photoelectric properties. Main research results obtained were concluded as follow.1. The recent developments in the research for carboxylate coordination compounds applications of triphenylamine-based materials in photoelectric area were reviewed.2. Four triphenylamine-based carboxylates were synthesized and characterized by IR spectra,1H NMR spectra, Mass spectrum and X-ray diffraction methods.3. Four carboxylates of the ligands can successfully coordinate to the organic metal-salt to form new complexes which were characterized by IR, Elemental analysises, X-ray diffraction methods.4. A systemic investigation on the properties of the ligands and complexes were carried out, such as UV, SPEF, CV and ECL. The analyses indicate that all the ligands and complexes were fine photoelectric properties.
