Abstract

Novel, squarylium dyes containing 1-(alkylcarbamoylmethyl)-2, 3, 3-trimethyl-3H-indolium groups were synthesized and their UV/Vis and fluorescence spectra, aggregation, photo- stability and association with bovine serum albumin were studied. The absorption and emission max wavelengths of the dyes in different solvents were in the range 619–653 nm. Compared to a typical ethyl squarylium dye, the introduction of alkylcarbamoylmethyl ...
