摘要：

A pressure-induced phase transition is detected in crystals of anthraquinone at approximate to 2.3 GPa by Raman phonon spectra. Related fluorescence experiments indicate a phase transition mechanism similar to that recently observed in 9,10-dihalogenated anthracene derivatives, leading to a less relaxed excimer state after the transition. Lattice dynamics calculations under pressure reproduce the observed phase transition and confirm the transition mechanism.
