Electron-Accepting Building Block for Benzobisthiazole Derivatives
4,8-Dibromobenzo[1,2-c:4,5-c']bis[1,2,5]thiadiazole (D4086) is a building block for the synthesis of benzobisthiazole derivatives. Its strong electron-accepting property and proquinoidal structure make it useful for developing functional dyes and π-conjugated polymers. Its cross coupling reactivity allows various units to be introduced into the molecule. Reported applications include air-stable n-type organic semiconductors¹)²)³), thermoelectric materials, and D-A-D type dyes with absorption at 750–1000 nm and emission at 950–1200 nm in the second near-infrared optical window, a region that minimizes tissue scattering and autofluorescence. Such dyes are investigated for fluorescence imaging, photothermal therapy and sonodynamic therapy.
