Bis(stilbenyl)squaraines - Novel pigments with extended conjugation
Meier, Herbert,Dullweber, Uta
, p. 1191 - 1194 (2007/10/03)
We report on the synthesis of a novel type of squaraines (11a-f, 17c) in which the conjugation of the chromophore is extended by stilbene units. These pigments exhibit absorption bands which have their maxima at the end on the Vis region and reach partly into the NIR.
