Abstract

Synthesis and examination of two highly luminescent oligophenylene derivatives of 2,1,3-benzothiadiazole with branching centers based on benzene-1,3,5-triyl units are described. These studies in combination with DFT calculations have shown that the presence of the branching centers causes differences in the absorption characteristics and similarity of the emission properties. High molar extinction coefficients (up to 15 × 104 dm3 mol−1 cm−1) in the medium UV-range and blue-green emission with quantum yields of 79-93% make them promising components of wavelength-shifting materials for optical devices.
