  Abstract:  The new hemicyanine dye, named 1,3,3-trimethyl-2-[2-(4-florophenylamino) ethenyl]-3-H-indolium chloride 1, was synthesized and characterized by spectroscopic methods (UV-VIS, IR, 1H-NMR) and by atomic force microscopy (AFM). The AFM data, obtained on thin films deposited on solid substrates, glass and mica plates, indicated that the hemicyanine 1 is aggregated as clusters containing thousands of molecules. These data are in substantial agreement with UV-VIS absorption spectra, obtained both in solution and on films adsorbed on glass or mica plates, suggesting that hemicyanine 1 is aggregated both in bulk solution and in adsorbed films on solid substrates.
