Herein, we report an anthracene-based material, 2-(anthracen-9-yl)thianthrene (2-TA-AN), whose crystal exhibits excimer fluorescence with an unexpected high luminous efficiency (up to 80%) and long lifetime (163.75 ns), due to pairwise anthracene stacking. These results will update the traditional view that excimers are poorly efficient in photoluminescence.
