  Extension of the Squaraine Chromophore in Symmetrical Bis(stilbenyl)squaraines

  摘要：

  The bis(stilbenyl)squaraines 6d-j,d',j' represent a novel class of NIR pigments. Their synthesis was performed by the regioselective 2-fold condensation of highly nucleophilic 3,5-dihydroxystilbenes 4d-j,d'j' with squaric acid (5). Depending on the substitution with alkoxy groups, the absorption maxima range in solution from 680 to 735 nm. Reflexion measurements in the solid state reveal an exciton splitting with maxima at about 670 and 1000 nm.
