A novel unsymmetrical squaramide-linked squaraine dye(SQ) has been synthesized through squaramide 3 and semisquaraine 6. The molecular structure of SQ has been characterized by ~1H NMR,IR and MS.Due to the influence of the hydrogen bond and the solvent effect,SQ exhibits unique spectral properties compared with typical squaraine dyes.For its excellent ability of binding primary amine,SQ is a promising receptor of recognizing primary amine.
