Abstract
Bis(2,6-diisopropylanilino)squaraine (1) was prepared by condensation of squaric acid and 2,6-diisopropylaniline. Treatment of 1 with trimethylaluminum affords a novel dimeric aluminum. squaraine complex: L-2(AlMe2)4.2THF.2toluene [L = bis(2,6-diisopropylanilino)squaraine] (2), which was characterized by X-ray diffraction.
