Reaktionsschritte

Compounds for introducing the unit (A3) can be obtained by reacting 9,9-bis(hydroxyphenyl)fluorenes with compounds (alkylene oxide, haloalkanol, etc.) corresponding to the groups R3 and R4. For example, 9,9-bis[4-(2-hydroxyethoxy)phenyl]fluorene can be obtained by adding ethylene oxide to 9,9-bis(4-hydroxyphenyl)fluorene, and 9,9-bis[4-(3-hydroxypropoxy)phenyl]fluorene can be obtained, for example, by reacting 9,9-bis[4-hydroxyphenyl]fluorene with 3-chloropropanol under an alkaline condition. In addition, 9,9-bis(hydroxyphenyl)fluorene can be obtained by a reaction between a fluorenone (9-fluorenone, etc.) and a corresponding phenol, and 9,9-bis(4-hydroxyphenyl)fluorene can be obtained, for example, by a reaction between a phenol and 9-fluorenone.
