摘要

•New benzothiazole-based styryl fluorophores from a straightforward and high-yielding synthetic route.•Positive solvatochromic effect in both absorption and emission spectra, and high fluorescence quantum yield.•Emission in the green-orange regions with a relatively large Stokes shift in the solid state.
