✦ Synopsis

Extended Conjugation in Stilbenylsquaraines.

-Stilbenylsquaraines such as (IX) and (XIV) are synthesized by C-C coupling reactions of the corresponding substituted arenes with squaric acid derivatives. The solubility of the squaraines is enhanced by dialkylamino and alkoxy groups. These groups also enlarge the intramolecular charge transfer. The extended conjugation of the stilbene units causes significant bathochromic shifts in the Vis/NIR absorption spectra.
