CRYSTAL POLYMORPH OF 9,9-BIS(6-HYDROXY-2-NAPHTHYL)FLUORENE AND METHOD FOR PRODUCING THE SAME

PROBLEM TO BE SOLVED: To provide a novel polymorph of BNF (crystal polymorph) that has an excellent heat stability or storage stability in a high temperature environment, and to provide a method for producing the same. SOLUTION: By crystallizing BNF from a mixed solvent of aromatic hydrocarbons and at least one solvent selected from phenols and ketones, a crystalline polymorph δ having diffraction peaks at diffraction angles 2θ=9.6±0.2°, 20.6±0.2° and 21.3±0.2° in powder X-ray diffraction pattern is obtained. The crystalline polymorph δ may also have diffraction peaks at at least one angle selected from diffraction angles 2θ=9.2±0.2°, 9.8±0.2°, 17.1±0.2°, 23.3±0.2° and 23.8±0.2°.

9,9-double (6-hydroxynaphthalene-2-yl) fluorene solvent compound crystal and its preparation

The invention discloses a solvate crystal of 9,9-bis(6-hydroxy naphthalene-2-group) fluorene and preparation thereof. A solvate crystal prepared from the 9,9-bis(6-hydroxy naphthalene-2-group) fluorene and acetonitrile is a solvate crystal I of the 9,9-bis(6-hydroxy naphthalene-2-group) fluorene, and a solvate crystal prepared from the 9,9-bis(6-hydroxy naphthalene-2-group) fluorene and ethyl acetate is a solvate crystal II of the 9,9-bis(6-hydroxy naphthalene-2-group) fluorene. The solvate crystal I and solvate crystal II of the 9,9-bis(6-hydroxy naphthalene-2-group) fluorene, which is prepared through the invention achieve the maximum melting endothermic peaks of 261-266 DEG C and the stacking density of 0.4 g/mL after being desolvated, is basically unchanged in color and purity after being preserved at 40 DEG C for three months due to high heat stability and has the advantages of high stacking density, good flowability and easiness for loaded material transfer.
