Donor-acceptor-dyes with extended conjugation, such as D–π–A–π–D type, are being intensively investigated as components of near-infrared (NIR) organic light-emitting diodes (OLEDs). In this communication, novel D–π–A–π–D dye, 4,4′-([1,2,5]thiadiazolo[3,4-d]pyridazine-4,7-diyl)bis(N,N-bis(4-methoxyphenyl)aniline), was synthesized by Stille cross-coupling reaction of 4,7-dibromo-[1,2,5]thiadiazolo[3,4-d]pyridazine. The structure of newly synthesized compounds was established by elemental analysis, high-resolution mass-spectrometry, 1H, 13C NMR, IR, and UV spectroscopy. The photophysical properties of the title compound were studied.
