The purification of phenanthrene is a prerequisite before studying its solid‐solid phase transition at the molecular scale. Two purification methods, namely, zone melting and co‐crystallization with 3,5‐dinitrobenzoic acid, were separately studied and compared, in view of reaching ultrapurity which means a purity of > 99.9 mol %. An explanation of the relationship between the efficiency of both techniques by using phase diagrams has been attempted. A novel strategy is proposed to optimize phenanthrene ultrapurification based on a combination of the two methods.
