Abstract:
Provided are a novel compound having a fluorene skeleton, and a method for manufacturing the same, the compound having a low palladium content or other content of a specific metal or content of a specific compound in a raw material alcohol, and being excellent in hue or various characteristics (optical characteristics, heat resistance, moldability, and other characteristics) as a raw material or in a resin that uses the raw material. This compound is a mixture of compounds having a fluorene skeleton represented by formula (1) (in formula (1), the rings Z being (same or different) aromatic groups, R1 and R2 each independently representing a hydrogen atom, a halogen atom, or a C1-12 hydrocarbon group which may include an aromatic group, Ar1 and Ar2 representing C6-10 aromatic groups which may have a substituent, L1 and L2 representing alkylene groups, j and k each independently representing an integer of 0 or greater, and m and n each independently representing an integer of 0 to 5), the mixture of compounds having a fluorene skeleton being characterized in that the content of elemental palladium therein satisfies formula (2) ((2): 0≤Pd≤50 ppm), and among the mixture of compounds represented by formula (1), compounds comprising the integers m=1-5 and n=0 are included in a range of 0-5%.
