Abstract
:
The synthesis and the absorption properties of methine dyes formed by Knoevenagel condensation of aromatic aldehydes with 1-dicyanomethyleneindane (2) afforded novel series of dyes (5a-k) absorbing in the region of 490-593 nm. The substituents on the aromatic aldehyde have remarkable effects on the visible absorption maxima of the new dyes. Increasing the solvent polarity had pronounced effects on the absorption maxima.
