Abstract
Metal binding is expected to make changes in photophysical and photochemical properties of sensitizers such as wavelength shifts and intensity changes in absorption and emission spectra. Perylenechromophoric dyes are excellent materials of aromatic π-conjugated heterocyclic family. The rigid structure of perylenechromophores causes strong intermolecular π-π interactions giving rise to versatile optical and electronic characteristics. With the advantages of tailoring the imide and bay-positions of perylene structures, exclusive benefits were achieved such as n-type semiconducting character, extended absorption coefficients, high photoluminescence quantum yields, self-assembly behaviours, thermal and photostabilities. A new perylenediimide dye containing powerful binding site for metal ions was synthesized successfully. The synthetic product was characterized by FTIR, NMR, UV-vis, Emission, TGA, DSC, and cyclic and squarewave voltammetry techniques. In addition, the photophysical and electrochemical properties were investigated in detail. The high thermal and photostabilities, including important photonic properties, make the new dye a potential candidate for various photo-sensing applications.
