4,4′-([1,2,5]Thiadiazolo[3,4-d]pyridazine-4,7-diyl)bis(N,N-bis(4-methoxyphenyl)aniline)

Donor-acceptor-dyes with extended conjugation, such as D-pi-A-pi-D type, are being intensively investigated as components of near-infrared (NIR) organic light-emitting diodes (OLEDs). In this communication, novel D-pi-A-pi-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, H-1, C-13 NMR, IR, and UV spectroscopy. The photophysical properties of the title compound were studied.

Automated summary

A novel D-π-A-π-D dye was synthesized through Stille cross-coupling reaction, and its structure, as well as photophysical properties, were thoroughly investigated in this study.
