Abstract

The synthesized benzothiadiazole-based series fluorophores as potential wavelength- shifting materials exhibit large Stokes shifts (> 160nm) with multiple broad absorbance bands from UV region to 600nm and a strong fluorescence peak around 700nm (in CHCl3). Intramolecular charge transfer (ICT) characters of the synthesized compounds are examined using UV–vis and photoluminescence solvatochromic shift measurements. Among the ...
