Acceptor Building Block for Developing Near-Infrared (NIR) Dyes
Share
4,8-Dibromobenzo[1,2-c:4,5-c']bis[[1,2,5]thiadiazole] (1) is an acceptor building block useful in developing functional dyes¹) ²) ³) and pi-conjugated polymers⁴) ⁵), owing to its strong electron-withdrawing property and a proquinoid structure⁶). Its ability to enable long-wavelength absorption and/or emission makes 1 valuable for dyes used in fluorescence imaging¹), photothermal therapy (PTT)²), and sonodynamic therapy (SDT)³), particularly those operating in the second near-infrared (NIR-II) region, which minimizes tissue scattering and autofluorescence. Additionally, 1 facilitates the development of pi-conjugated polymers for high-mobility organic thin-film transistor (OTFT) materials⁴) and thermoelectric materials⁵).
