摘要：

Novel symmetrical bis-squaraine dyes have been synthesised, in which two squaryl moieties are conjugatively linked by a phenylene or biphenyl unit. Such linkages produce significant perturbation of the absorption and fluorescence spectra in comparison with analogous symmetrical mono-squaraine dyes.
