T-shaped push-pull chromophores: First modification of the indan-1,3-dione-fused benzene ring by cross-coupling reactions

A series of eight novel T-shaped chromophores with indan-1,3-dione central acceptor moiety and peripheral N,N-dimethylamino and thiophene donors were synthesized. 4,7-Diiodoindan-1,3-dione was prepared in a straightforward manner from phthalanhydride. Its modification with donors was accomplished by Knoevenagel, Suzuki-Miyaura, and Sonogashira reactions. Target push-pull chromophores were further investigated by X-ray analysis, UV/Vis spectra, and theoretical calculations. Georg Thieme Verlag Stuttgart, New York.
