Pick of the bunch : Banana‐shaped molecules 1 and 2 containing dimethoxybenzene and pyridine units are highly efficient emitters of violet light despite the interruption of the π conjugation because of meta substitution. The contrasting solvent dependencies of the fluorescence quantum yield values of 1 and 2 are explained by the disparity between the difference density distributions in the excited states of the molecules.
