Abstract The synthesis of several 1,3,6,8‐tetraethynylpyrene derivatives is reported. The effect of extended acetylenic conjugation on their absorption and fluorescence‐emission properties is studied. Significant bathochromic shifts of both the absorption and fluorescence emission bands are observed. These derivatives emit fluorescence in the visible (400–550 nm) region.
