The novel anthrene, 9,10-bis(2-(1-methyl-1H-pyrrol-2-yl)vinyl)anthracene (MPVAn), was synthesized and fully characterized, which shows a significant aggregation-induced emission (AIE) phenomenon. In solution, it hardly emitted fluorescence. But in solid state, its fluorescence intensity reached hundreds times of that in solution. In order to understand the AIE mechanism, the photoluminescence behavior of this compound at different solution viscosity and temperature was investigated. The results show that the AIE enhancement is due to restricted intramolecular rotation. Excited at 420 nm, the powder emitted a pure yellow fluorescence peaked at 562 nm with a full width at half-maximum of 66 nm. Electronic properties were investigated by UV-Vis absorption and cyclic voltammetry. The highest occupied molecular orbital and the lowest unoccupied molecular orbital were found to be -4.78 and -2.28 eV respectively.
