摘要
Squarylium dyes based on 2,6-di-tert-butylpyrylium and 2,4-di-tert-butylpyrylium nuclei have been synthesized and characterized by elemental analysis, H-1 NMR, IR- and electronic impact mass spectroscopy. The dyes exhibit high melting points, good solubility in organic solvents and absorption maxima in the range of 711-763 nm with high extinction coefficients. (C) 1999 Elsevier Science Ltd.
