Abstract:

Squaraines are interesting organic molecules due to the strong absorption in the visible region (e ~105 M-1•cm-1), intense fluorescence emission and good photoconductivity presented in these dyes. These features make them useful in a variety of applications in the area of imaging, nonlinear optics, photodynamic therapy and photovoltaic cells. Furthermore, squaraine dyes are suitable for fluorescence detection of proteins at longwavelength excitation and labels in biological assays due their unique photochemical and photophysical properties namely light absorption in the visible red and near-infrared regions. This work describes the synthesis of squaraine dyes prepared by the condensation of heteroaromatic compounds with a dialkyl ester derived from squaric acid in a one-step reaction.
