Experimental and theoretical methods were used to study newly synthesized thiophene‐π‐conjugated donor–acceptor compounds, which were found to exhibit efficient intramolecular charge‐transfer emission in polar solvents with relatively large Stokes shifts and strong solvatochromism. To gain insight i...
