| titleOfInvention | Compounds having a fluorene skeleton and methods for producing them |
| abstract | PROBLEM TO BE SOLVED: To provide a novel fluorene having a low content of a specific metal such as a palladium content in a raw material alcohol and excellent in hue and various characteristics (optical characteristics, heat resistance, moldability, etc.) of the raw material and a resin using the raw material. A compound having a skeleton and a method for producing the same are provided. SOLUTION: A compound having a fluorene skeleton in which the content of sulfur protozoa in a compound having a fluorene skeleton represented by the following formula (1) is 200 ppm or less. (In the formula, R 1 has a hydrocarbon group which may contain a hydrogen atom, a halogen atom or an aromatic group having 1 to 12 carbon atoms, and Ar 1 and Ar 2 have a substituent having 6 to 12 carbon atoms. May be aromatic groups, L 1 is an alkylene group having 1 to 12 carbon atoms, m1 and n1 represent the same or different integers of 0 to 4, m2 and n2 represent integers of 0 to 3, and m1 + m2 ≧ 1. However, m1 + n1 is an integer of 4 or less, and m2 + n2 is an integer of 3 or less.) [Selection diagram] None |
