Abstract The synthesis of a complete series of nine soluble distyrylbenzenes (DSBs) with two (2a− c) and four cyano groups (1a− f) attached to the peripheral aromatic rings is reported. They were prepared by the Wittig reaction and characterized by 1 H and 13 C NMR, FT-IR, UV/Vis, PL, EL, mass spectra, and elemental analysis. The optical properties have been studied in detail to monitor structure− luminescence relationships as a function ...
